Help! Bought a 1993 Four Winns W/ 5.0 OMC Cobra Motor and Drive - Losing power after crusing

Not bad ideally you want a warmed up engine & throttle wide open, I think they’d be higher then. Next leak down test and what did the air pressure test show? If all is good test your manifolds & try running it again. See if you still get water in the oil. Air pressure test is really the most important

The air pressure test is losing psi somewhere. I cant hear anything, smoke test didn't reveal anything. Thought maybe I could hear something in the valve cover but hard to say. I think it might be my setup, it is just a rubber ball that inflates and if I pump more then 12 psi it shoots out of the hose

You have to get a better seal for a valid test

It just occurred to me that the previous owner installed a new distributor cap. He mentioned something about timing being out but he had a mechanic look at it. Wondering if that relates to my original issue.

Probably wired it to the wrong firing order
