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

    How long should I let the pressure test go for? And what's an acceptable loss I also ordered a smoke tester, figured it'd be good to try that as well. How would I operate that? Same way as the cooling pressure system?

    Add in a dry power steering pump as well lol. Looks like I'll be learning how to rebuild an engine potentially. There's a first for everything I guess. I guess I'll tell my wife very well unfortunately be no boat for this cottage trip :(. Unless I can figure out the issue and patch it up in a...

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

    Yeah it held 15 psi. It's slowly crept down over about 5 to 10 minutes but I think that was the plug I was using to pressurize the system. I had to leave town for a few days so I put a bunch of WD-40 penetrating fluid in all the cylinders. Going to retest compression when I get home. I guess...

    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.

    And I would be pressurizing into the thermostat housing correct?

    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?
