Explanation of importance of clean Flame Arrestor solved my problem that I have been working on for 2 weeks. I have had multiple boat people help me and they did not figure that out. I had flooding in my engine. The combo of the Needle and the flame arrestor worked. thanks
Well thank you very much for watching the video my friend! That is so awesome ! simple easy fix!
Thanks for the info.. my flame engine was running rough and stalling. Flame arrestor was pretty dirty. Pretty sure its all good now
dlarremore thank you for watching the video 😊 I’m not sure if you have the same engine as my but I also change my spark plugs every 3 months because I use my boat a lot and man this thing is like a monster that eats spark plugs.. I have hurth transmission on my boat so they start making weird noises where the engine is not running so good so when I can hear my transmission I know it’s time for a tune up 😊 I hope it helps. Thank you again
Great vid! Merc 470, same issue. advice worked great. Thanks!
Thank you for watching 😉👍
Excellent video from Michigan!
Thank you for watching 😊
Great stuff, your explanations simplify things.,,,Thanks!!!
Thank you watching and stay safe! 🙂👍
my starboard side mercruiser did the same today. Ran great then as I slowed down in the channel the engine stalled out and couldn't put it in gear w/o it stalling.
Check your ignition system. Distributor cap and rotor, spark plugs, spark plug cables. You are probably running short a spark plug or two, from there on, fuel pressure and stuff but easy pease you have her straight in no time! Thank you for watching the video 🙃
Congrats from Spain
Thank you for watching 🙂
Great Video and nice boat.... Florida?, hi from Yukon, Canada, stay healthy :)
Yeah Fort Lauderdale 😊 thank you for watching the video 😀
Nice video
Mike Noneya thank you for stopping by 😊
My engine hesitates and dies when I give it throttle, I really have to pump it back and forth to get it going but once it's on plane it runs great. Coming back to idle twice I heard a pop in the spark arrestor. Cleaned the spark arrestor, seafoam, and some carb cleaner, but didn't fix the problem. Bought a new fuel water separator and carb rebuild kit on the way. Doesn't look like there is a fuel filter in the metal coupling to the carb on my 4.3, maybe prev owner took it out. Just got the boat in March, been running great until about July 4, and it has just gotten worse and worse.
Thank you for watching the video bud! Well you are going to right direction.. backfired can happen on a lean mixture to but more often than not the problem resides on the rich side, take your distributor cap off and and check how it looks down there it’s probably time for a new one and check your ignition timing because if it is even a little bit off can cause backfire and spark plugs and wires should be one of the next things to, The last thing on this list would be your fuel pump failing and at that point right there you have done a full service and you probably will have reached the problem, the next thing that would cause backfires will be bad valves and stuff but don’t think that should be a problem, it’s usually something simple
That belt looked like it was bent backwards over a gear at one point, is replacement belt rated for that type of load?
Great video thanks.
Cole Diffin thank you for watching the video 😊 the belt only goes backwards on the tensioner quite easy to replace and the load of the belt should be good because I went to west marine and asked for the belts for my engine but again can’t trust anyone 100% 😂
Thanks bro , good video
Thank you for watching 😊 the hard work is definitely worth it 😆
It's better to take advice from someone that's on their boat , showing you the exact same thing you'll be looking at that's already learned by trial and error ,, be safe bro
I try to pass the message that if you get the boat you can fix it lol just get the boat 😆 thank you for watching
I feel for you I have 1 7.4L to take care of not 2 like you, I just did a refit last year, put in a long block with new exhaust and a full fwc system no more corrosion, with a industrial heat exchanger
I did switch mine to a fresh water cooled system and I have to say I do sleep better at night LOL but mine is a half system so the engine is cooled by antifreeze but the full exhaust system still gets salt water. I was told that the half system cools a little better than the full close loop but I guess not enough where would actually matter.
Do you have bravos or straight shaft?
Thank you. Where is the flame arrester. Is it carb cover
Thank you for watching the video my friend and Yep it’s that piece on the very top of the carburetor
Thank you for watching the video my friend and Yep it’s that piece on the very top of the carburetor
Hey I notice that your carburetor has a plug on the bottom of it? What’s that for is that a drain plug? I’ve got one in the same spot on my 4.3 mercruiser but it has a rubber hose that extends 5 inches out plugged by a spark plug (previous owner smh) so I thought it connected to something at first but now think it was plugged in the first place and the plug was lost. Anyways I’m rebuilding the engine and want to make everything perfect. Lmk what you think bc the plug is right next to the adjusters just like yours.
Hello my friend thank you for watching the video! If you’re talking about that rubber cap on the front middle bottom of the carburetor , That would be used on a automotive setup, if I’m not wrong that connects to the vacuum port of the transmission or something but on the marine application you don’t use that port that’s why it’s capped! But on that port you can also check your vacuum for the engine, that is probably why you have a 5 inches hose capped on it where you have that spark plug is where you connect a vacuum gauge to check the vacuum on the engine, on the very end of the video I’m checking the vacuum pretty much with the same little bit of a hose like the last owner left on your boat, nothing to worry about but that needs to be capped well so your carb don’t lose vacuum, what carburetor do you have? The carburetor number should be on the bottom front on the carb, The two marine grade ones are the 1410 and 1409, some rebuilders plug that port for the marine application because we don’t use it but the the Delbrock carburetors are pretty much the same casting just different jets and stuff so if you buy a 1409 that has that bib nothing to worry about just cap it ;-)
Cruising the South THANKS SO MUCH, I really appreciate it and love all of your videos!
😊 Anytime my friend! just glad to help!
What size edelbrock carb is that? I’m looking to change my carb I bought it and the holly 800 is way to big and just bogs out looking for some advice it’s a mercruiser 5.0 Thanks
Hello my friend thank you for watching the video! here’s a link of a video of mine of how I choose my carburetor there is a little math included on the video that you can calculate how much CFM do you need it’s related with your cubic inch and your top RPM, I stepped down from a 750 as I was to run to rich on a 454 but I only cruise at 3200 RPMs so you need to consider that ;-)

Hi is me german i have the same engine and carburator but mine at 3000 rpm goes upand down to 2600 by it self but if i run it at 2100 rpm the engine stay stadi doesnt go up or down stay at 2100 rpm what do you think it is ?
Hey German! Could be your fuel pump failing! If it has more then 100 hours on it put a new one and as you at it take a good look of your fuel lines on the vacuum side (before the pump) for any possible air leaks also good chance to do spark plugs and wires and distributor cap and rotor for good measure lol right there you good for the season on my opinion 🙂
Is this what was happening?
czcams.com/video/T1V7ahxhUU8/video.html
I'm sure you don't but for others. Don't use ethanol fuel..
May as well replace fuel filter at the same time.
I sometimes do lol ethanol free at marinas here the prices are ridiculous so I usually use normal gas till I find a cheaper marina 😕
Good video mine's doing the same thing when I started your video I was like I don't know about this guy then you said f*** it and I was like okay he's cool definitely knows what he's doing😁✊️ not being sarcastic
😅 thank you for watching I appreciate it, my friend! I wish you all the best I hope you get everything sorted out ;-) once you are down there maybe Slap a new distributor cap too I had a friend of mine‘s boat that his flooding problem was related to his ignition system which wasn’t my case but that does it too. have a great day and good luck bud!
Can you fix my motor? We have the exact same motor
Hey Bryce thank you for watching the video 👍 well my friend I do this as a hobby not as a job but I will be glad to give you my two cents 🙂 what is going on with your engine?
@@Cruisingthesouth I have twin full inboards. I just bought the boat with one engine working and the other one isn't connected ant all. And it's missing the carburetor fuel lines and the spark plugs aren't connected. I just need someone to tell me what parts I need to buy and then somebody to hook it up for me
Hit up ( Bills marine parts ) by state road 84! These guys can get you anything you want also they will provide you some help! Go there with tons of videos and pictures show him what you need he will put you on the right path
@@Cruisingthesouth thanks I'll check that place out. I'm in South Beach so it's close by.
if that belt only lasted 2 and a half months there is something wrong, I would of bought 2 and have a spare of all belts
Thank you for watching the video :-) I know right it must’ve been a old stock item or something because since I replaced it I have had no more problems
@@Cruisingthesouth you should keep extra belts or a adjustable belt that will fit any size
Just a heads up, that Edelbrock carb is not a marine model. Edelbrock makes only two models 1409/1410 and that's neither, get the right one before things go real south. Also that belt is wrong, V belts can't be back run over a pully, only a serpentine can, someone has made some nutty mods. Find a good marine mechanic and get those engines check over. And yes it dose take a expert to boat safely.
Megan Perry thank you for watching the video but no mods have been done like for starter it’s a 1406 eldelbrock carburetor on top of a mercruiser 454 so nothing is going south there and serpentine belts require serpentine setup and that’s not how mercruiser set it up on this engine on this year. go to west marine with my vin number and that’s the belt you will get. But thank you for you expertises
Megan Perry You had me questioning my parts guy really good LOL I had to look it up but yeah I stand not corrected, on the 1994 Mercruiser 7.4 L they did not use serpentine belts back then so I do have the correct belt. Just figured I would post this here in case anyone else goes through this situation to. But thank you for your input to me and I really appreciate it and I’ll most likely take your advice and upgrade my carburetors to the marine grade which I really don’t see the difference but I guess it must be one but like I said before I am not a experienced mechanic But I had boats my entire life and the point of the channel is that if I can do it anyone can do it and I’m out on the boat every weekend and because of my preventative work I never have problems out there. These Mercruiser’s engines take a lot of maintenance but if you do maintenance them they run so good for a very long time. Once again thank you my friend
@@Cruisingthesouth OK, so the edelbrock 1406 is not for marine use, it's a 600 cfm automotive only, the equivalent in marine is the 1409. On a big block I would go with a 1410, it's 750 cfm. Just looking out for the safety of you and your passengers. I think the seawater pump belt should also rout over the motor circulation pump pulley, they look to be in correct orientation, the idler pulley looks like it's from a serpentine setup. I would check with a mercury dealer and or the mercury parts web sit. Safe boating
Megan Perry Thank you for your input but without any Disrespect you must be looking at it wrong because I have the full service manual and the engine is set up to the T how it’s supposed to be.. The 1994 454 Mercruiser DID NOT have a serpentine belts. I get these engines serviced over and over again all following the service manuals this just must be a different engine that you were thinking of.. subscribe to the channel I’ll make a video of the way it’s set up and I’ll show it on the manual ;)
@@Cruisingthesouth megan is right about the carbs. The 1409 and 1410 are the only coast guard approved edelbrock carbs. They look similar to the automotive models but the marine carbs have several safety features built in, like often a return fuel line, sealed off vacume ports and corrosion resistant finish to name a few. Its certainly worth the investment. Automotive carbs can malfunction and flood, spilling fuel into your bilge and cause an explosion. Here is an brief article that really explains the differences well.
