I cant help you with that. im not really an engine guy, but i am trying to be since I just bought a junk boat and had to basically take the whole powerhead off the other day. maybe you could go by a shop and ask how they test them... maybe search on the internet for a forum.

either way the hardest I could blow is 2.4 on my calibrated electronic gauge. that doesnt seem like much to test leakage.

Ok, thanks. I might be able to help you with the boat motor, I've repaired a handfull of them. Let me know if you need help.

I think I got it for now... of course. the powerhead gasket was blown and another small piece was cracked, seemed to be causing it to foul the plugs on one of the cylinders. one plug would be extremely dry and the other extremely wet. now, both are equally moist. of course I changed the plugs, plug wires, rebuilt the carb, and changed a coil in the process of elimination. luckily a friend of mine who is a excellent boat mechanic (retired) advised me about the powerhead gasket and kinda helped us change it. Good experience, and now I am not too worried about tearing down the motor and stuff since we had to take the lower unit and all of that down to get the powerhead off. its always been my motto that if I am capable of doing the job I will do it myself as you just never know what you are getting into with a mechanic shop.
