    And yes I want to find the problem instead of mask the problem.

    Thank you. I’m going to clean it tonight with some MAF cleaner and see what happens.

    2002 Crownline 5.7

    I was unable to find the map sensor. I probably just overlooked it. I checked for vacuum leaks and I had no luck there. Again I could unplug the IACV and it ran perfect. I assumed if it had a vacuum leak that caused the erratic idle it would still do it even after I unplugged the IACV. Idk maybe...

    2002 Crownline 5.7

    The customer stated that the boat would die (only sometimes) when he would bring the boat back to neutral. I checked it out and found it was loping (kind of like it was loading up) and ended up unplugging the idle air control valve and it never acted up after that. Naturally I thought the valve...

    Manifold/riser 3.0 mercruiser

    So I found that the manifold is cracked. Pretty bad it seems. Didn’t take too long to pour water into the cylinders. Mainly the 4 cylinder. Now I’m at a crossroads because I have a feeling there is more than just that with how hot it got. I tested the compression and the front 2 cylinders were...

    Manifold/riser 3.0 mercruiser

    If the riser gasket is bad, could water enter while running also? Or just after shut off.

    Manifold/riser 3.0 mercruiser

    Ok thanks. Actually the engine got hot. So there was no water in the old oil. It had a grayish color to it. Not milky at all.

    Manifold/riser 3.0 mercruiser

    Yes it was higher. The engine originally got hot. I know it could be the block, head, head gasket, or manifold/riser. I was just unsure of how a manifold could let water in. I mainly wanted to know if the manifold could leak water into the engine while it was running, because the oil was new and...

    Manifold/riser 3.0 mercruiser

    I have a 3.0 mercruiser that is getting water in the oil and I know it could be a few different things. I’m in the stage of dissecting it now. I put new oil in it and ran it on muffs for about 15 minutes, shut it off checked the oil and it was a mud looking color. My question is, can someone...

    Ok thanks.

    1986 3.0 mercruiser

    The engine got hot and is now getting water in the oil. Is there a way to test to see if it’s the head gasket, head, or block without tearing it down one by one? Maybe a way to pressure test that will help determine?

    Chevy 305 mercruiser

    I have a Chevy 305 that ending up getting so much water in the oil that it started spitting oil out of the dipstick. What’s the best way to check the head gasket and block without tearing it all apart first? Is there a way to pressure test the whole engine to help determine where I need to...

    2024 wake pro 230

    Ok thanks. I hadn’t either but with it being new I thought maybe something had changed.

    2024 wake pro 230

    I changed the coolant before storing it last fall but I spoke with a dealer and they said they run a summer blend coolant and it only protected down to like 20 degrees? I am going over it for the summer and I’m not finding anything that says that. Does anyone know? The orange coolant came out of...
