Prowler launch was normal with normal warm up. Idled out the channel and went to accelerate. Got about half way up and BOOM! Dead in thw water. So when I got it back home, I pulled the O/D and took it to my mercury mech. As soon as he saw the drive shaft, he told me I had spun the engine coupler. I said HUH! Then he started digging out metal with the grease while explaining what happened. He initial analysis was something broke in the O/D that locked it and that in turn caused the coupler (next weak link) to spin. So I have to pull the motor. Something I have been wanting to do but really had no reason. Going to update everything I can while it is out.

Primarily looking for help on a cam upgrade. While I got it out might as well improve the performance if I can. Would like to go with something a LITTLE hotter/stronger then the OEM 502 roller cam. My mods are in my sig. Any help or suggestions or actual experience would be greatly appreciated.
