    1987 OMC cobra 2.3 won't turn prop.

    About says it all. Engine running, engage into gear, prop won't turn. Is there any sort of shear pin in the out drive that would go? Any theories people? Thanks

    Breaking news 1 on 2.3 water in oil.

    In trying to narrow down where the water came from (other than the non existent riser gasket) I fabricated an aluminum plate like the thermostat gasket and siliconed it both sides installing it between the thermostat housing and exhaust manifold thereby isolating the two. I removed the hose...

    What to replace a 2.3 with.

    2.3 exhaust/cooling question.

    In diagnosing water going into the crankcase, I found that when on the muff it's going into the cylinders. I know this may be a cracked manifold from a freeze, but also yesterday found that a bolt (one of 4) at the riser to manifold junction is broken. My theory on getting lucky is that this...

    1987 OMC 2.3 water in oil diagnosis.

    Yes, I've read them all both here and across the world ;-). But people here are nicer! Subject says it. Oil has been drained (all three gallons). I thought it would be the block, but core plugs are in place (yes I know that's not the definitive answer) and I put it on the muff without...
