Yamaha 4 Stroke Outboard Engine Carb Rebuild Series [4] Component Reassembly

Part four begins with the cleaning of all of the brackets to ensure a good mating surface. There was a large amount of buildup of grime on all surfaces where o-rings meet, After which it was time to swap out the remaining O-rings before assembly. The assembly bolts and washers were also cleaned. The hose I had to cut earlier needed to be replaced and had arrived for this swap-out.
One side of the carb, with the thinner O-rings had trouble. 93210-35M86 did not seem to fit correctly on the carb. I had some real concerns about this one and opted to clean and reuse the existing ones.
The silencer box, bolts, washers and brackets are staged for reassembly, adding the carbs and temporarily securing them with m6 bolt until everything looks good and tightening down to the back bracket. Torques down from the center outward.An inspection through the carbs is done to see that none of the o-rings shifted during assembly, after which all remaining hoses are reattached and cable tied.
Finally, the accelerator pump is installed onto the assembly. all hoses routed as per the service manual and the linkage reconnected. Finally the common throttle linkage is reattached to the four carbs completing this portion of the project.

Very informative. I rebuilt my carbs on 75 hp Yamaha by watching your first 3 video's. I couldn't wait till the rest of series came out but you got me on the right track. It runs like did 20 yrs ago. Thanks. God bless you and yours

Next will be a quick Segway to rebuild the fuel pump before the last chapter.

Great series. I didn't realize it was JUST posted now I gotta wait for episode 5!! :) I was curious about the carb rebuild kit. Do you need 1 for all 4 or would you need 4 for all 4? Looks like a lot of o-rings but not all the jets for example. I recently picked up a project 2000 T50 that I need to take the carbs apart and clean up. I wanted to order some parts ahead of time just to be ready. Thx

Reeealy good video. i need help to find some used carbs for a f60 outboard because mine are almost destroyed and the brand news are very very expensive. If someone knows anything i whould be greatfull.

[@delorean1]

Did you try dropping them into an ultrasonic cleaner

[@quintonmuna]

How do you adjust the idle to make it rev a little more? Do i have to adjust the idle screw on all the carburetors?

My engine won’t idle. Only runs when choke is on at about 3/4

[@delorean1]

The engine has no choke. Your high idle setting must be off….
