why are you running the prop out of water? Now you have also damaged the strut bushings and the stuffbox. Both require water to luberacate them during operation. Does it run rough or back fire a lot?

You may have floated a valve(s) which can mean one or more valves hit a piston and bent the valve thus causing the valve to not seal. Do a compression check on all cylinders. If low/no compression, pull the head(s) and get a valve job performed. You can also visually check to make sure you did not knock a hole in the top of a piston.
FWIW: "floating a valve" means that the valve spring is not stronge enough to react quickly enough to the high RPM and thus does not close the valve in time and the piston comes up and hits the open valve. |

Yeah, what David said, do a compression check first. I did a 180 real hard one time and pulled the prop out of the water but no damage. I don't jump wakes with my Mustang. ------------- Tim D |
