I'm just guessing my hp. I have no clue. But the motors are milk duds anyway. The guy had 540 heads on this motor with no cause for them. I had broken comp. ring in one cylinder also. I know these motors are smoked. No crosshatching either. I'm running 28 bravo 4 blades. And I did run 77 in this condition. I have no reason to lie when I'm asking what it should do.
