    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

    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...

    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

    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...

    Rough idle and dies when put in gear

    I have a 1998 mercruiser 305 and the engine was removed to repair some power steering issues and now occasionally it idles rough and dies when going into gear. Any ideas at what I should be looking for? Thank you.

    Mercruiser 305. Water in cylinder.

    One day on the water the boat starting missing and would only get on plane occasionally, but had this terrible tapping coming from the driver side of the engine. Sounded like a lifter tapping. Got it in the shop and pulled the valve cover to make sure the rockers were not working their way...

    2001 Crownline alarm

    Do crownline boats have a delay switch for the alarm? (Doesn’t power it up for say 60 seconds) So when you turn the key on the oil sensor doesn’t automatically go off because it has no oil pressure until the engine is running?

    2001 Crownline Alarm

    I am working on a crownline that has the alarm go off when the key is just in the on position but not running. When it’s running the alarm does not sound. It is the oil sensor causing this (if I unhook it, it stops beeping). The owner said it just started this last week. I installed a new sensor...

    No start question

    I have a 78 cobalt with a 350. You can run it for maybe 30 minutes, or sometimes maybe 5 minutes, and once you shut it off it won’t start until it cools down. And if it starts it won’t plane out. Idles fine. I have ruled out fuel by using a jug once it starts acting up to bypass the tank and...

    1992 ski centurion 351w

    So this year my boat started off not wanting to start. I thought I had narrowed it down to the coil. Its numbers were a little out of specs with a multimeter but not bad so I changed it. Once on the water it started cutting out like bad fuel. Got some heet, and fuel treatment hoping that would...

    Water pump kit

    I have a 1973 Johnson 65 HP and I'm trying to find a impeller kit with orings and seals, but I'm having no luck. I have found the impeller just by itself but nothing else with it. I need the seals as some of mine are looking rough. I found this kit but everywhere I see it it says that its only...

    Trim hoses

    My friend was going to change out his trim hoses due to one leaking but before he could replace them his house was destroyed by a fire and therefore the hoses burnt up as well. He is dealing with a lot and asked me to go ahead and fix it for him. The problem is I don’t have anything to go off of...

    79 Cobalt shift interrupter

    The shift interrupter had not been working but I was able to find and fix a wire that wasn't allowing it to ground the igntion. Now I adjusted the lower and upper shift cables to factory spec, but when going from forward to neutral it kills the engine unless u rock the shifter. Reverse to...

    1979 cobalt shift question

    A friend has a 1979 cobalt mercruiser gen 1 and it will shift from neutral to in gear just fine but will not shift from in gear to neutral while it's running. Once shut off it will go into neutral fine. Not sure what would cause this?

    2012 Axis

    Why would a hole get blown in an exhaust manifold with no kind of warning? Motor never got hot but it was like the manifold wasn't getting enough water maybe?

    2012 Axis water in oil

    My friend has a 2012 Axis that the engine got hot in and now has water in the oil. He took to a reputable marine dealer and they tested the exhaust manifolds and said both of the them were bad and causing the water to get in the oil? I'm not saying there lying but can someone please verify this...
