yeah ill be doing it a little here and there but i am a tech at the nissan dealership now. i sold the mower shop and moved to the country bought a 3bed house on 3 acres on a lake. i call it my semi retirement. went from 200k to 80 so its been an adjustment.

[@user-qw2uh2tw2g]

thanks for the info, i just used straight muriatic acid did the job ty

[@boatdude12]

Thanks for the video

[@rockynymia]

What’s that acid you were using

[@CluelessEngineer]

I have pretty much the same motor. Appreciate the bit about the rubber swelling up from carb cleaner. I'm going to remove that seal first if it wont break on me.

[@smallengineguys]

Good luck!

[@CluelessEngineer]

@@smallengineguys so I just did everything and put it all back together. Fired up in a barrel of water no problem. Is it normal that the engine isn't peeing? Is it only supposed to spray water out after it gets hot? Or is it always supposed to spray water out when it's running?

[@smallengineguys]

always sprays. sounds like bad impellor.

[@CluelessEngineer]

@@smallengineguys turns out it was a wasp sitting in the hole so that's fixed. After carb clean the motor runs for a minute or two and then dies by itself. It starts can barely handle idling and if I push the throttle arm it'll rev up then die as soon as it can. I'm thinking bad fuel pump because gas been sitting in it for 2 yrs. Any ideas?

[@smallengineguys]

@@CluelessEngineer sounds about right. If you prime it up again does it run again?

[@dabbotube]

Is there a video on how to access the fuel filter on this outboard, I can’t seem to find one

[@shanehankins4051]

Thanks bother

[@smallengineguys]

Welcome

Hey does anyone know the name of the part that sits below the fuel hoses, and screws onto the bottom Carb? It’s some kind of linkage and I think it’s missing a piece that connects through a square hole.

[@chanlerblackmon5305]

That would be your choke knob

[@paulwallace2263]

No oil tank? Did you remove it and mix?

[@smallengineguys]

It wasnt there. This was a customer.

[@SatashMitusingh]

How do you set the timing on the 50hp yamaha

[@smallengineguys]

2 stroke? its the flywheel key that sets the timing.

[@neonnight34609]

[@teddymello68]
