I have the Acme 2271 15" x 15.75 4blade prop with a 105 cup.
Performance, RPM's and GPH are better than the previous 14.5 x14.75 OJ prop
I could get on plane with 700's in back locker, 400 in walkway and 400 on top of bow seats. Factory front ballast filled and 7 people in the boat.
Once ECU adapted it got up no problem.
