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

    I figured it out I had it open going back to the drive. Capped it off and now pumped it up. It's holding 15lbs psi

    I have my pressure tester hooked up this way. That line leads to the freshwater intake. My tester has a bladder on it. If I cover my hand over where the hose came off I can hear water bubbling somewhere but no pressure holds.

    I have it hooked up to the hose that comes off this which leads to the intake on the thermostat.

    I'm not sure if I have it hooked up right but it sounds like it's coming out from under the intake manifold. I hooked my tester into the hose off of the water filter I'm assuming it is. Pump air and I can hear it around under the manifold or maybe by the bell housing. Hard to tell.

    I've never been this deep into a motor. But I don't want to be completely out of 5 grand so I'm willing to try. Seller actually sent me back 1,000 because he felt bad.

    Sorry for all the questions. I'm going to pick up a cooling system tester now. Once I get it hooked up, am I listening for where the leak is coming from? And how much psi should I be putting in?

    Blown head gasket? How would I check for that without a leak down tester. I don't have a tester or air. Already this far in I'm thinking of just pulling the heads
