    3.0 omc engine mating to mercruiser outdrive

    Pretty sure the only issue he may run into is the coupler , which depends on what generation engine and outdrive he is using. with the 1990/1991 cut over they went from a crankshaft hub bolted coupler to one that bolts to the edge of the flywheel. also Will need to use the merc manifold and...

    Pink Super Tech (Walmart) -50 RV and Marine ok for engine?? I always thought NO...??

    the main issue is with the cheaper ones using denatured ethanol for most of the freeze protection vs propylene glycol is the ethanol is harder on rubber components and has a higher tendency to loose concentration over time vs the higher cost ones. I boat in upstate NY so same thing gets very...

    Yes quicksilver is mercurys brand that they sell outside their dealer network. Same parts part numbers except for a few digits are the same no issue , it’s just a matter of knowing what you are getting into. Is the hull riveted or welded ?

    Winterization difficulty

    Its much easier with drive off. Taking the drive off seems like a big deal until you have done it. You need an alignment bar to algin the engine and drive when you go back in. Worth looking at the coupler while engine is out as now is time to replace it. Again double check your stingers and...

    Recommended parts

    Before you get too far into it ($$$) drill your transom and stringers. Check the gimbal bearing for smoothness , if rough replace. Look at the ujoints, inspect the bellows and do the water pump. given the age of the boat the bellows likely have been done so they may still be ok. Bellows and...

    Winterization difficulty

    the outdrive it self in the down position is self draining as long as the drain holes are clear. I spalsh some af in the prop hub to take care of any residual and if you leave it outside you should cover the prop ub so no snow/ice or leaves get in. If you are worried about a new to you boat...

    Strange exhaust behavior during winterizing

    as bondo mentioned it come up through the manifold bottoms and out the risers. The separate hoses feeding the elbows supply cooling water to the exhaust when the thermostat is not open. This is a warm manifold system vs the cold manifolds with only the supply to the manifolds that is supplied...

    My block is drained, right?

    you can always pour some AF in the thermo and it will come out the block drains eventually. After I drain mine then put the plugs back in, take off the hose coming up from the outdrive (at therm hsg), I have a short piece of old cut off radiator hose that has a 90 in it so it points up easy to...

    Alpha 1 drive quick question

    is that why the ladies call you 50 cent? Yeah I don't know either. Was assuming they dont just fall out? or did yours corrode?

    Alpha 1 drive quick question

    My concern would be if it froze and pushed out the Welch plug I assume you didn’t water test the boat ?

    cold weather break in

    When I bought my new GM long block from Michigan motorz a few years back they insisted on rotella T4 conventional 15W40 for break in. Also wanted conventional oil for first 100 hrs before switching to synthetic Your lower temps may play into it but I’d think you’d be fine using it. Long block...

    Shift shaft seal / carrier seal / oil o-ring?

    normal this time of year, goes dormant unless someone has a project going. If you dont have it get manual 14 for the gen 2 drive very helpful/good info

    Shift shaft seal / carrier seal / oil o-ring?

    do you mean you have lube leaking down the shift shaft in the bellhousing onto the lower ? This may be from the poppet valve in the gear lube line. If you dont pop the drive on quickly any residual lube in the line will leak out when the drive is an inch or so off the bellhousing.

    Shift shaft seal / carrier seal / oil o-ring?

    no good deed goes unpunished... On my entire drive the only seal that was somewhat compromised by wear/age was the shift shaft seal. All other seals were in nice shape, except for the prop shaft seal with fishing line... So you had no leaks - just replaced the seals while you were in there?

    Shift shaft seal / carrier seal / oil o-ring?

    I tried just replacing the seal on the shift shaft not the whole plastic housing it is in, could never get the seal to to stop leaking , ended up buying the bushing with the seal in it. Sierra is better than most aftermarket parts, but the OEM is best in my experience. My boat is a 2004. two...

    Thermostat GLM13230 OEM # 87290A4

    verify the thermostat is opening, would not be the first time a new one didn't work. Put it in a pot of water see what temp it opens at and if it opens fully.

    Shift shaft seal / carrier seal / oil o-ring?

    most likely the carrier seal below the water pump. relatively easy to split the drive remove the water pump and pressure test the lower by plugging the hole where the quad ring goes. Usually can clamp a flat piece of metal on it. Get 12-15 psi of air pressure in there and put soapy water on...

    Out drive water flow incorrect?

    where it connects to the lower is not what I was talking about. There is a clip farther up the tube that holds it to the bellhousing casting. The clip goes into a 1/4“ hole in the bellhousing , i suspect this where the water is coming out. you will have to look farther up in there than where...
