I have a 04 Yamaha 50hp - 4 stroke, how often should the valve clearance be checked/adjusted? What about the timing belt? The manual says about every 100-200 hours. Why do these things have to be checked so often? Never need to check valve clearance in a car engine and timing belts last for 70-120K miles. I do realize that a boat engine is under a different type of load than an automobile, but it still seems a little funny. Or should I just live with it and buy an E-tec (or that style 2 stroke) next time?
