[bsh21wash]

I have a 74' 100HP Evinrude outboard on a 16FT Riveria Ski boat... I want a prop that would suit my needs for pulling people behind the boat. Any suggestions would be greatful thank you -Brian

Re: Prop question

Usually for pulling power you want a lower pitch than what you'd normally have for cruising. Depending on how much you want to pull, I'd start with a 17 or perhaps even a 15.

Re: Prop question

It refers to the pitch of the prop blades bsh21wash.For example a 15" pitch prop in theory will screw 15 inches long per one revolution.Of course there is a percentage of slippage in water,hence the theory.A typical 15" pitch prop for your engine will be classed as a 13 3/4 X 15 prop.The 13 3/4 is the circular diameter of the prop and of course as mentioned above the 15 refers to the angle or pitch of the blades.
