    No power under load Yamaha F40 outboard 4 stroke

    A 2002 Yamaha F40 hp outboard has no power under load or even when just "goosing" the throttle in neutral. It happened like someone flipped a switch. Plenty of fresh fuel, fuel pressure and volume are fine. I hate to say I did this, but if you give it a shot of starting fluid while...

    Market for jet skis for parts?

    I have a 1998 Yamaha Gp800 Wave Runner and it needs a cylinder, maybe a cylinder head, a piston and the carbs and fuel pumps rebuilt. Is there a market out there to sell this as a parts boat? If so, what do you think it might be worth? I'm afraid that most people looking for parts are pretty...

    60 HP Mercury 2 stroke outboard has lean misfire

    Oil consumption issue

    I recently acquired a 2000 150 HP Johnson that seems to have excessive 2 stroke oil exhaust smoke on cold start-up and during warm-up. After it has been driven and "blown out" 2 cycle smoke seems normal. Are these outboards known for this or is there likely a problem with the oil injection system?
