1976 SPORT 15 40-HP
Posted: Sun Jul 18, 2021 6:04 pm
Recommend a propeller for a 1976 SPORT 15 with a 2008 Evinrude 40-HP engine [of unspecified model, unspecified gear ratio, unspecified maximum engine speed at full throttle].
I recommend a three-blade aluminum propeller that will allow your 40-HP engine to reach its recommended maximum engine speed in RPM [which is unknown to me} when at full throttle on your 1976 SPORT 15 with a light load.
Do you have any good data about the boat's current engine speed and boat speed?
What propeller is on the boat now?
What is the engine model?
What is the engine gear ratio?
What is the recommended maximum engine speed range at full throttle?
What is the manufacturer's recommended optimum engine speed range at full throttle for best power output?
