I'm not sure about this but here is my confusion.
The outboard is a 1986 75HP 2 stroke Mariner, the boat is a 15ft bass boat, the current aluminum prop # 48-77344 A40 17P aided with a doelfin returns 5500 rpm @ wot.
When the doelfin is removed the boat struggles to get on plane in a manner that is inconsistent with the norm.
The engine is in great condition, no other performance issues other than the afore mentioned.
Should i be looking at a prop with different pitch?
