    Fuel floating on water arond running engine.

    A friend has a 90 hp 2003 Mercury 2 stroke and it idles a little rough and leaves excessive fuel floating on the water. The fuel is coming out of the exhaust. Anyone have any idea what is wrong? I am a fairly decent shade tree mechanic on my Yamaha 40 but have no knowledge of a Merc.

    Motor is a Yamaha P40 1998 2 stroke. My question is, does this enrichment valve have any influence on the performance of the engine after the engine is warmed and the valve shuts off? Example, if the valve diaphram has a small tear in it, will it effect the idle or WOT after warm up? Thanks...

    No warning buzzer

    I own a Yamaha pro 40 with factory tillar, trim and tilt. I say factory tillar cuz my model number indicates it is factory ,P40tlhw. Evidently it has never had a warning buzzer or lamps.

    Waterpump on P40

    Hello, I have a 1998 P 40 yamaha 2 stroke. I have owned it for the past 7 years. It has the original waterpump. Would it be a good idea to put in a rebuild kit just for preventative reasons and how often should this be done? I fish an average of 3 days a week year round so I use it a lot. BTW...
