I have a 1971 Mercury 7.5hp outboard. Ser # 3200882. I need to replace the prop. I connot locate any numbers on the prop itself. Since the motor is original to the boat, is there a better prop choice that might provide better thrust?
Well, without any info regarding current prop, rpms with current prop, no info as to what boat it being used on... The infor is on the prop somewhere.
Your choices for props are limited to 7, 8, and 9 inch pitches.
