    Mercruiser - 3.7 ( 470 ) Alpha1 ( please list the sources of CLEAN water in the oil ) about a cup - Antifreeze not leaking - no green in the water -

    Even though you have closed cooling your exhaust elbow is still raw water cooled, correct? This could be leaking at the gasket between the manifold & elbow or via a hole in the elbow to from the water side to the exhaust side.

    1988 Bayliner Capri with a 2.3L OMC Ford cobra

    Not knowing what is in there, hard to say, but I always used Dex from the auto parts store I had to change that P/S actuator a few years ago, made a mess while it was leaking for a couple seasons. Removed the exhaust on both sides for access and had to get this cotter pin removal tool to get...

    1988 four Winn horizon 200

    The other thing I wanted to mention is that when I replaced the deck I had the 'glass shop gel coat it in non-skid gelcoat, I did NOT want carpet on a wood cored deck, sealed all the holes to mount seats. IMO carpet is death to wood cored decks, all it does is hold moisture, that rots wood. And...

    Sound deadening

    In a boat nothing sounds better than a V8. Yesterday I was out on the bay and heard the howl of a go-fast going & coming while I was out.

    OMC did use the Ford small block with the Cobras but the bell housing & engine mounts are both different. At this point you have to decide if you want to switch the whole thing over to Mercruiser. If you get the right deal on a drop in it’s the way to go. I like the Cobra it’s been very good to...

    Or…eventually repower to a V8 then you won’t want to muffle it!

    1988 four Winn horizon 200

    Most of those boats came with either a 4.3 V6 or the 5.0 V8. I would stick with Chevrolet power whether you keep the Cobra drive train or convert to Mercruiser which will make your life easier. You’d need a post 1986 SBC, one piece rear main seal, could be pre-Vortec or Vortec. I have the 4.3...

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    Yep that sounds like what happened. Once you get it set up right it's not hard to keep it shifting well. Starting with a new cable, cleaned out pivot housing, all adjustments done you should be good. With all the bad press OMC got on these I am amazed at how reliable this boat has been. And...

    Yes check very carefully for rot, especially if it had plywood decks covered in carpet. Mine had the deck replaced in 2007, outside painted in Imron 2012 and top end engine overhaul in 2017. It's a good running stable boat, I will gladly repower it when the time comes.

    Check the terminals on the back of the gauge for power & ground. If good then check the tank sending unit.

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    Either that or get an older boat last year without cats. I’m keeping this one as long as I can when the time comes I will just get a reman 4.3. Cheapest way to do boating even though here Id also be better time wise off with an OB, I do know my way around the old Chevy small block. Nothing...

    2015 Motor MerCruiser 4.5L 250hp NO EC - OVERHEATING!

    that's why a cat converter equipped inboard is a no sale for me. Not when I have to replace manifolds every 5-7 years. Especially because outboards get a pass on that.

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    PS those instructions are basically what I followed but I used the OMC tools that were not yet made when those manuals were published. I have an OEM 1988 Manual and the pix & procedures are basically the same. The typical problems are: cable jacket cracks, lets in water, cable gets sticky gasket...

    1989 Bayliner Trophy OMC 5.8L - Help with new boat

    Yes you need to be on the prop side make sure the keys are out of the ignition first! You will be able to feel if it locks in Fwd & Rev that way. The best way to get the right cable is to use the model number. These were on a sticker on the engine valve cover or thermostat housing.
