- Ever wonder how hard it is to check out your impeller? We took a 90/65 Mercury Jet motor and reflashed the ECU to produce almost 115 HP! We also upgraded thie customer's boat to a stainless steel impeller. This is especiallly helpful with the hole-shot! Stay tuned to our results video to see how this improved our overall performance of this model 1648 with a Mercury 90/65 outboard jet motor! 434-846-8823 www.RiverRoadJetBoats.com

The time it takes to be this wise and to have the willingness to do such high quality diy jet informative content is absolutely priceless 👌. Thank you guys!
Jeepers kriepst! Its Chris Farley!
May I add, it’s a good idea to keep a magnet in your tool kit for when you’re doing this in the field.
I'm glad I am not the only one who runs 2 feet off the gravel bar! Great video! I have a 21' Jetcraft with a Merc short stroke 200, (2 stroke v6) . I have a 4 blade stainless impeller in my pump as well. Not that it rely makes a difference, but the factory clearance spec for the impeller is 0.030" for the aluminum and 0.015" for the stainless steel. You can take the angle from the wear ring and chuck your impeller up in a lathe to square up the edges of the impeller. Just remember to barely take any metal. Just enough to make it bright. I have also used 400 grit wet/dry sandpaper laid in the wear ring and spin the impeller by hand against it to remove little dings. I also clean up the leading edges of the impeller blades with a file on the top of the blade only at about 45 degrees, just enough to clean them up. Tuning your impeller like shown on this video make a big difference. I thought I would share some tricks I have picked up along the way. The money on gas alone is well worth the job. Thanks for the great video. I subscribed and will be checking out the rest of them.
You have the only video on CZcams on this subject here. Thank you greatly for the info..
Thanks for the help on doing this fix.Nice boat by the way.
Awesome video!
Did anybody ever find out who did the ECU flash?
Just stumbled upon your channel....very good stuff. I'm currently running an 1860 Alumacraft w a 50hp Merc 4 stroke, with a 6" Micro Jacker. I'm leaning towards upgrading to a 2072 platform so I could run the 90hp prop, and then convert the lower end over to jet in late summer if needed. I'm just trying to gather up as much info as possible. Any suggestions would be greatly appreciated!!!!!!
I've done the same with my 1652 running a 40hp prop and 50 jet. Favorite setup so far, will run upriver 26mph with the jet.
You can use those butterfly washers over and over lol where you went wrong was you used a hammer to completely smash them flat. You don't need the hammer period! Only need the screw driver to open the butterfly washer up just enough that the nut spins free lol that way you don't weaken the crap out of it like how you did it.
Hello Sir......Very informative video! Question......where did you get those two handrail /lean posts? (Shaped like "T") on the bow & stern deck.? I have had 7 surgeries and they look like they would help my balance on my boat......... Thanks
NRS sells them its just the shipping is crazy cause its so big. but give me an email if you would like pricing. office@riverroadjetboats.com
Those tabs on those lock washers break easy.. only bend them enough to get the nut off.... I always kept extras too.
Just wondering how the Yamaha compares to the same size Merc. on the top end. Had a G3 1860 dlx 90/65 Yamaha with 3/4" uhmw bottom added and did 28 mph loaded.
I run same motor, get 40mph when set up right.
Curious about the flash. I also have a 90/65 do the 115/80s and 90/65s have the same impeller? Assuming you did this with a prop motor you would need to change the pitch of the prop is that the same with jets?
That's a great looking boat. I'm interested in more information on the boat. Who can I contact?

What were the updated speed numbers after the impeller install?
what is that nozzle on the lower unit? whats that do?
Hey Jeff, that’s our patented nozzle system to turn the outboard Jet into all the capabilities of an inboard but with the serviceability of an outboard. Better steering and efficiency.
Who is the company that did the Ecu work?
I want to know this also.
Is the butterfly washer the lock washer?
I need a job and a boat. Where are you all located
How do we get a flash done? Very interested.
That is a nice layout of the boat, what is the length and width of that boat Mason?
Who done the ecu flash
I don't even have a jet but was interested in the mechanics of it, good explanation.
What are the ECU mods?
