    5.0GXI water infiltration

    When I took the engine apart there was water in the oil but not milky, so it must have got in when engine was off. The bearings looked like they were nearly brand new. This was the original engine with around 450 hrs on it. It for sure came in from the exhaust somehow. The manifolds are fairly...

    5.0GXI water infiltration

    I have the engine pulled and apart. The manifolds looked normal. all the cylinders had water in them and the rings are rusted to the cylinder walls. I want to figure out what happened before I put a new motor in to avoid this happening again.

    5.0GXI water infiltration

    I have purchased a 2005 Four Winns 288 w/ twin 5.0 GXI engines and Volvo DP-S outdrives. One of the engines has taken in salt water. My question is, do the DP-s outdrives have an exhaust flapper in the y pipe to stop back flow of sea water. The exhaust manifolds and risers have been replaced and...

    OMC King Cobra cooling issues.

    Also I was incorrect, the manifolds are also raw water cooled. I was thinking of another boat. Too many projects.

    OMC King Cobra cooling issues.

    I replaced the risers however the old risers looked great. They came off a freshwater boat, but I replaced them anyway. Now I have a different problem. I am getting water in the bellows/gimbal area. Is there a gasket for mounting the outdrive on the King Cobra. I have a regular Cobra mounting...

    OMC King Cobra cooling issues.

    We run in saltwater mostly. I don't recall if I changed the risers when I did the manifolds. It will run for 30 minutes @3000 rpm before losing any coolant.

    OMC King Cobra cooling issues.

    Only the risers are raw water cooled. The manifolds are fresh water cooled. Manifolds are new last year when the new long block was installed. Oil is clean and shows no sign of coolant. I will try and do some pressure testing next. Thank you for the info.

    OMC King Cobra cooling issues.

    HI, I have a 1992 OMC King Cobra with a 5.8l ford engine with a closed cooling system. The issue I am having is, after running the engine for a while the coolant overflows the heat exchanger causing engine to get warm. The engine is a new long block and I normally run it a 2800 to 3000 rpm for...

    7.4l oil coming from exhaust.

    It is in a 340 Searay Sundance and shoehorned in next to another motor. Very little room.

    King Cobra outdrive seal

    I have a 1992 OMC 584dpeamh 5.8l with a King Cobra outdrive. Is there a seal for mounting the outdrive to the transom mount? The parts beak down does not list one. How do you keep water out of the bellows? Any help would be appreciated, Thanks.

    7.4l oil coming from exhaust.

    I have a Mercruiser 340 inboard that is getting water in the oil and oil coming from the exhaust. I replaced the intake manifold gaskets that appeared to be torn. I flushed the oil out several times but still have the oil in the exhaust. This is a fresh water cooled engine with fresh water...
