A family friend use to keep his jet boat at our dock. Lucky me. He gave us kids rides and took us skiing. It was a 454 corvette engine with a Berkeley jet. Sometimes he ran dry headers on it. When he did the lake patrol would try to catch him. He never got caught unless the patrol just sat at our dock waiting for him to return. Days before the cell phone. He called the house and asked if they were waiting for him. If we said yes he found somewhere to hide out for awhile. A couple times he just beached it. The boat was a chick magnet. Unfortunately for us kids who want to ride in it all the time. When I skied behind it he loved to tease me noand throw a roster tail. Let me tell that hurts. I thought I would be a smart ass and try to ski though to the side. Lesson learned. This was in the late 70s and early 80s. On West Okoboji lake. Ron Van Pelt was the owner of that awesome jet boat. He gave many rides to people. We did get turned in for catching ducks with a fishing net. But always let the ducks go right away. Great times growing up. Ron also raced cars. Every once in a while when I tell this story about Ron ( we called him Itch) someone will remember Ron or had a ride in his boat. If you happened to be someone who got to meet Ron please tell me what times did you get to meet him and if you rode in his boat. Would love to hear about it. Unfortunately we lost our friend a couple years ago. I really loved Ron he was an amazing guy. I remember his gas petal was a big bare foot. Ron was like my second dad. I will never forget those fun years growing up on West Lake Okoboj with uncle Itch! Naturally I have a obsession with jet boots now. Hoping someone to mean another person who knew Ron! Happy boating everyone!
Totally BS! He is on a lake. There is no getting away from lake patrol. The very idea someone would risk that for a loud header ticket, dumb story and sounds like u are pretending to be that made up character in your mind.
Growing up int the 70's on the water was so awesome. My parents had dear friends who owned a jet boat with an blown Old's 455. It was so rad. This was a blue metallic flake finish with this huge motor sitting there with the blower and supercharger. It was about a 28 footer I believe. But once it was up and planed out, there was only the back 5 feet touching the water, and that was occasionally. The owner would ski barefoot while his wife drove the boat. I remember riding a thing called a Torpedo that was shaped like a hotdog and you could actually steer to one side or the other. I would get off to one side, cut it hard to the other when a large boat would pass us and jump his wake, sometimes coming six feet out of the water. How can a kid grow up today without those kind of stories?
1:23 Pat always has to sport the pen protector, that's his thing :)
The foot throttle doubles as a "dead mans switch" so when you get thrown overboard, the boat doesn't keep on going, like with a conventional hand throttle in a boat.
Yes it will keep on going, even at idle it will usually be faster than you can swim. I put on a lever throttle and a tethered kill switch, better and safer.
@@walkingman9171 For high speed I think a pedal is better than a stick.
Great video my 440 powered 1973 southwest gt is a blast these boats are getting rare these days I would love too see a revival of these jets!
buybouçníc boat 2 440 hp jeys 40 moh olús
Finnegan said come get ya sum boys 😂🤣👍
Game over is one bad ass jet boat.
game over goes faster backwards lol
Made for someone 4' tall lol dudes knees were hanging outta the boat lol
That's pretty much most drag boats from the 70's :D
Pat for someone who's a land lubber, you drove that beast like a boss. My two cents : stay the heck away from those things since they're dangerous as hell for a Noobie especially w/ that much H.P.
Safer than a V Drive. This is much better for a noob
Jet boats are the street rods of the lake. Sure other boats are faster, turn better, whatever. Who cares. Gearheads who own boats want something that sounds like their car and a bass boat doesn't sound or look like this : 1:45. I enjoyed this episode
1:10 I freakin love that part lol
Funny how he said just kidding I know it's a big block ford when it's a chevy
Pocket protector in the life jacket was a nice touch.
"It dosent turn well at all" well from a fellow jet boat enthusiast, they do, but you need the balls to give it power in a turn! A jet boat only tunes, and turns under power! Also , use the place diverter under turn, point it down! no rooster needed to turn!
good times back in the day when jets ruled the lakes and rivers
Finally a boat episode!!!! I have a 1973 Donzi Classic 18 if you guys at PowerNation are interested in messing with a vintage race boat. #holmanmoody #1973 #donzi #donziclassic18
dunzi çllisxc 22 çudey cab v8 jet rive 65 mph pus
As Carrol Shelby said "Too much horsepower is just enough!"
Funny seeing"pocket protector Pat" in the boat.....lol.....
My Big block Ford 460 Jet Boat would Turn on a Dime! Something is just not right? Maybe it's the Hull? Or the Driver! LOL
You might wanna re-position those seats farther back lol.
Jet boat 101, you got to gas it to turn it. With proper footwork that thing will turn on a dime.
Great to see Pat's packing some pens in the life jacket
Let's face it, he'd be out of balance without them
Sweet boat guys.
I like fast power jet boats.There fun to ride in.
What else besides Coors on a lake in the mountains, a big block Chevrolet , with Weiland supercharger to give you the real rocky mountain high
Never been a fan of a jet drive (poor handling and slow, let alone a cigarette butt will clog them up) stern drive will get you the most out of the big block.. What’s up with the steering wheel in the wrong side, that was odd? That foot throttle can be a trip with that set up (jet drive and a big block) I’ve been on the Ohio river for over 40+yrs and love boating. Us ol boys have a saying about boating..
Break
Out
Another
Thousand
Expensive hobby for sure. Great show like always guys!!
If Pat adds one more thing to his belt, we will need to contact Batman, to purchase a "Batman Utility Belt"....
No stop signs no speed limits nobody's gonna slow me down
Had a boat like this but less power. Great fun
Jet Drive Boats actually are the only ones that have brakes, You can switch from Forward to Reverse, even at high revs, the thrust will then slow you down very fast
With that kind of Increase in Power, you might want to consult with the Drive manufacturer about an Optimal Impeller. That kind of HP should be putting you closer to the Century Mark, even taking into account the Inefficiencies of a Jet Drive
You wouldn't want to be going 100 in one of these old Mod-vees, these hulls were never meant to go that fast. Can they ? yes they can with about a 1000hp. BUT the driver would be playing with fire at that speed. IMHO If you want to go 100mph in a Jetboat safely get yourself a Gullwing or a Tunnel hull.
I've hit the water at 50....my ass did ragdoll cartwheels 5 times before i sank, that shit isn't soft at all so 80 mph is scary as hell
yes no faßter theb ⁵0 mph
It’s probably hopping because of the trim. Play around with it and you should be able to ride much smoother
Pats jowels started flapping at 60mph lol
That motor is probably making nearly 700 to 720 because the air on the lake is much cooler and the engines out in the open sucking in much more air than it would in a car or on a dyno
But I would assume the humidity in the air would counteract the cooler air? Just guessing I have no boating experience.
Imagine having 680HP and only going 80mph.
Seems fast, till you meet a V-drive of similar power.
@@bigboreracing356 LMAO!
Think Pat was a little nervous at first. Looks like he had a blast afterall.
A big fan from Libya
You should cover shrader's performance boat with 1000hp. It's coyote powered 💪
Naw they need to cover finnigans game over. Like a 750 cubic inch Sony Leonard hemi.
Awesome boat
Put hydrolox steering in it it will drive and steer a lot better.
Wow! What a incredible rock video! The music was rad! Chief, I clicked this as I wanted to hear the engine and learn something about this boat. Disappointed
Pat... dude... stay w the girls in the campsite
I've always wanted a Tahiti but flat bottoms are so unsafe. I've seen a few high side at lake mead in the chop only going 40 mph and it's not pretty.
Grew up with a supercharged 455 olds jet boat, pretty embarrassing to get smoked from the line from a dude with a 150 merc outboard. Very loud and cool looking but...
Ya but olds motors are boat anchors.
15⁰ hp jet outbatd beßy
Jet boats crack me up.....and the insane money people will dump in them. A bass boat with a big outboard prop engine will pretty much beat any jet boat in existence.
But that sound!
But you can run a jet boat on a wet sponge (very shallow water) where the bass boat will encounter expensive damage.
@@bigboreracing356 I 100% appreciate your humor on that but just to be clear, $70K would be for a brand new boat and trailer rig. Just checked my local craiglist. Found one that is pristine at 15 years old with a 250 Evinrude with clear titles to boat and trailer, for $19,500.
@mindeloman - One time (years ago) I was on a very crowded lake, returning to pick up my downed skier. One of those ever-present gremmies on a jet ski came off and went under my boat as I was turning. Everyone was horrified. I cut the throttle, and searched the lake anxiously. He popped up, with no harm done.
Had there been a propeller, I would've needed a fishing pole, since he would've been chum.
When you factor in maintenance / repair costs (car engine - compared to touchy and temperamental outboard - not to mention the respective drives),
initial cost for a nice 450 Horse auto engine - compared to well... how much was a 450 Horse outboard?,
places I can go, that a propeller just won't,
and the safety factor,
your statement is just silly.
BTW - I have always thought how stupid an entire line of 4 or 5 outboards on the transom looks, when the same job can be handled easily by one or two automotive engines.
@@mctigmctiggy1475 - My boat is GAY??? And you're just telling me this NOW?
What are you, 15?
I doubt you even know the difference in a v-drive and an outdrive. Hint: a jet drive is neither.
Put it in the car and much more fun😎
Figured it would hit 100 at least. Bass boats with 300hp outboard hits 80’s with no problem.
and no girls in sight
What do you guys mean: "the boat doesn't turn so good"? These things will turn on a dime! the only problem is, it will throw the Driver & Passenger overboard while doing it.
They don't call them kidney busters for nothing.
Jet propulsion is about the most inefficient way to move a boat, 680hp with a propeller would be fun.
rickystewi Completely agree but that thing doesn’t have enough transom to hang a bravo drive on.
@@thisismyalt9010 is a surface drive a no go too ? I have no frigging clue of the requirements to install such drive.
never had anything to do with Jet boats? Jet boat racing throws your whole argument out the window. But they were actually invented in new Zealand by a mr Hamilton,who saw the need for a drive set up that wouldn't get knocked off in the Rocky Rivers.
@@Mercmad race a screw against a jet! Prop wins
wribfé
lol wonder how many passes they did with that before the residents were coming out. dont think you get a big block ford WAT'n around there alot
You guys need to do a spot on finnigans game over jet boat.
Maine is the best place on earth
It is like a LITTLE sports car; where you feel like you should hang one of your legs over the the side. I be you really need to pull a fuel barge behind it to keep its tank(s) filled.
Why RiteStuff on an intake???? Good luck getting that intake off! At least it won't leak!
Wow, all that power in such a small boat and it's a turtle. Jet propulsion is so unbelievably inefficient!
wr⁸ñg
@@sharonbraselton4302 no, unfortunately I'm not wrong. I've been doing this for a long time and when you make an apples to apples comparison the jet drive just plain falls short
Guys your two high speed electric trim tabs (steering connected) a high capacity impeller and a bolt for a rooster tail short of show and go. It may turn like crap now but that's all you are from spins tighter than a Saturday night drunk. Newbies lol
....what?
Hole in the water to throw money in.
Damn only 80 mph that can't be right I had an old bass boat with a merc 150 two stroke that would run 70. Seem like that thing should go a lot faster.
@@bigboreracing356 yep and your not getting any ass on a bass boat
wribg
😂😂 whats funny is most tournament bass boats will run 80 I know my cousins does
ive been over 80 in a skeeter many times
@@bigboreracing356 Obviously they do. They buy them in sufficient quantities for them to be manufactured and marketed on an industrial scale. You seem awfully desperate to defend the obviously subpar performance of this boat. What insecurity is it you are trying to compensate for?
yeah but no girls want to ride in a bass boat.
20:02, bummer dudes. what are the numbers?
The balls on the end of those lifters, Can they possibly snap off under Hi- boosted application. aka-Toast - Cleetus McFarland????... I love how scientific & thorough he gets when measuring volumetric displacement, Teaching us laymen! Just the way an engine builder should be! AWESOME!!! What a shop teacher/engine builder!!! Worth his weight in gold!!! Just the person I would want building any engine for me!!
the color thou
No water valve for the headers?
he increased the horsepower and didnt change the impeller to compensate the increase. That looks like a Jacuzzi pump which more than likely has a B impeller, you more than likely needed a D impeller judging on the fact it was only running moderately faster than when it had the original engine. With 680 horsepower that boat should be in the 90s and you were barely running 80. My 18 foot Hydrostream with a 200 Black Max would run off and leave you.
nó ót wint
only ñeed merçy 200 sport jet
This VS Finnigan's twin turbo Hemi boat
Looks so uncomfortable as hell. I would rather have a party barge
If it wasn't a JET it would go A'lot Faster.... And be a REAL BOAT....V DRIVE
Completely useless on all but the most calm days.
What mph did it run in the boat??
Specs on the CAM please
Not water injected headers
Wow! From Maine myself, beautiful place to live. Just way to damn expensive to live there.
cool
Why in the hell did they keep the jacuzzi pump that pumps an anchor for a motor like that where’s the berkley swap? this was painful to watch non jet boat guys do this where’s finnegan when you need him
Cool
How long can a fresh built engine sit before it would have to be through again?
As long as you tear down and oil the bearings and cam forever fire it up dry and it will die
He alludes to the boats poor handling, I have driven two and both turned very poorly. I can relate to the comments about driving skills but they do steer like a beast.
What is the gorgling sound..
The motor.. Nah... The vibration of the gasoline tanks...
680hp and gets passed by a bullet with a 250
Seems kinda slow for a such a big engine, you can get a 150HP two stroke outboard in the 60-80mph range depending on the hull/prop, is that just cause its a jet boat and less efficient?
60-80 mph ??? On what boat? Jet drive is way more efficient at producing thrust.
Perhaps impressive in 1974
You noted rpm makes boat go faster how does hp come to play would high rpm small block acually go faster
You need horsepower to get rpm, it's both.
So what's the difference between a marine and a regular engine?
one goes in a boat
Are Earles hose and lines (5:42) coast gaurd approved? (they need to be or you are in violation operating a vessel that is noncompliant) You might be sorry upon inspection by authorities... Just an experienced boat mechanics observation.
@@bigboreracing356 You haven't grown up on the water. The Coast Gaurd has rules (treated like law) for every part of a boats power plant. You don't mess with the Coast Gaurd, they will tow you off the water and hand you over to the local authorities real quick. And I am familiar with Earles products, first class for sure but without the proper classification numbers (often required to be printed ON THE HOSE) this a is poor example to make. The CG doesn't care how good you think it is, they test and certify all and boaters must comply or face fines....... just fyi
@@bigboreracing356 Happy New Year! My video clearly states the technique is for disassembly only and shows a method of removing the spring without a compressor. Not everyone has them. My statement about the jet boat is 100% true. You are also correct that on most inland lakes he would recieve no scrutiny from authorities unless he was driving carelessly. And while the same thing could be said if he were driving in the Saint Clair river (an international waterway) near me the standard is much higher here than in a small lake.
I see go fast boaters get towed in and fined every summer, mostly after authorities witnessed dangerous driving technique and then checked them out for compliance in other areas usually starting with safety equipment, of which water hoses that connect through hull are included..
Let me be clear I think Earls hose and plumbing products are first quality. I also think it's slightly irresponsible to recommend non-conforming products for marine use no matter how good they are. I agree you'd be hard-pressed to find a better quality hose but in the relatively unlikely event that your boat got scrutinized by authorities you could be subject to some fairly expensive fines just for something silly as having the world's best hose installed on your boat instead of one that the coast guard deems legal. I've grown up boating an international waterway and have 50 years experience running a boat on the saint Clair River I don't mean to belittle anyone or any company but knowledge is power.
@@bigboreracing356 The video was shot years ago when there was no free tool rental yet and only uploaded a few years ago. And although I have that option today many still have no nation wide chain auto parts store nearby. REALLY?
Nice boat. Be ssfe
People don't get jet boats, all these comments are funny about your bass boats and outboards. Jet boats are like driving a 66 GTO. Does it turn well? No. Does it stop? Nope. Is it fast in a straight line compared to modern cars? Negative. Is it comfortable? No. Top speed? Slow.... but is it cool? Absolutely. Anybody can go buy a new outboard, these are hot rids, built not bought, and each one is unique.
qr⁹bg
That old-school glass boat is severely limited in top speed by the old, heavy fiberglass construction, non-matching jet pump & old hull design. If that engine was in the modern Canadian-made Outlaw Eagle aluminium built, semi-tunnel design with the right pump...that 680 HP engine would break you into the 100+ MPH range easily.
Jet boat. 🤣🤣🤣🤣🤣🤣🤣🤣 75mph 🤣🤣🤣🤣🤣🤣
@@bigboreracing356 if they only new.
wrong
@@sharonbraselton4302 My bad, 70mph with the wind. 😆
looks like fun for about 10 minutes, what do you do after that?
John P. Get more gas!!
drink beer, swim, check out hot girls, drink more ect.
Almost 700hp and only 80? Lame... I've seen new bass boats with 300 Merc do 80 mph lol
Boats do not have Transmissions they only have one gear
Jet drive loses efficiency
Impeller needs to be set to peak torque, otherwise it'll just rev out with no added mph
They have no idea how to drive a jet boat let alone a boat of any kind
Charles Torruella Ok
Why don't you volunteer to show them. Let's see a few vids of you driving jet boats, I'd like to see your pro level driving skills.
Never driven a jet drag boat. We do own a 50’ CIGARETTE AMG that moves right along. Much different I imagine. Seen top fuel boat’s take off 8,000hp BLOWN HEMI’S. 0 to 60 in 3 seconds on water. That what ya call HAUL’N THE MAIL. Lotta respect for those drivers👏👍
Any TV host that refers to a jet boat like this 18' Glenco Jet boat as: 'A chunk of metal flake' does not know S#!T about Hot Rod Ski Boats and/or V-Drives. End of story.
whàler 18 beyer
ràge
Is it a big block or a jet?
lol both the "jet" is a water jet turned by the big block
That thing probably doesn’t track very well on turns.
That's called power slide fun. lol
LLLLLLAME!!! Talk and music over the engine sounds. If I wanted to hear a pathetic guitar or idiots talking, I would have titled a search for one.
2:12
Bunch of ninny's
Never understood these jet boats. They are so slow and inefficient.
noppé
I no
Actually with a jet you do have a braking system. Throw diverter in reverse and that boat will stop on a dime. With an in out unit you will have a boat load of broken gear teeth.
