I have a 1969 115hp Evinrude that came with my 89 Bayliner Arriva. It does not have a prop. What size and pitch is recomended for my application. If more info is needed please let me know and I'll do my best.
Turning Point Propellers is suggesting a 21 inch pitch prop. Here's the link where you can enter the information for yourself. http://www.turningpointpropellers.com/
