I am a new member here. I just purchased a pristine 1987 Montauk that has a 1987 2 stroke Mercury 70 hp outboard. While the motor and engine are in very good condition the propeller is a little beat up. The engine presently is mounted with a cavitation plate even with the hull bottom. I have read that I should move it up 2 holes so the cavitation plate is about an inch to 1.5 inches higher than the hull bottom. I will be running this boat in some choppy water and may need to maintain plane at lower speeds. I am also looking to get decent fuel economy. Top speed is not too important. Can anyone recommend a prop for this combination? I look forward to start contributing to this forum.
