You gotta buy hp, unless you have a small boat like Cam, your yamy is a copy of my Johnson, last of the big looper mods and carb, they are bullet proof, mines a 130 hp, only prob in 12 yrs of owning is a new fuel pump/ oil injector, $700.00 worth, I reckon KY jelly would be a good lube for any Merc.
