Re: What props fit a ’79 Evinrude 35?

My understanding is larger diameter is better when pushing (more thrust) big loads and small diameter is better for light go fast boats. I’d suggest going for smaller diameter and then select the pitch to get the motor reving at the top of it’s rpm range with it loaded at it’s lightest load. That way the motor won’t over rev. In the small go fast boat that you are talking about it may be that adding even one passenger might change the optimum propeller. A working tachometer tells all.
