I just bought a 97 40hp yamah last night (model 40tlrv). I put the motor on my 16 ft. polar kraft jon boat. I bought the motor with no prop and I am very confused on what pitch to select.
Here are my two questions: Correct me if I'm wrong but the owners manuel recommends 4500-5500 RPM when running wide open. How do I find out what the rpm's are at if I have no gauge? Also, if anyone has a similar setup can you tell me what type of pitch has worked best for you? Thanks
