    95 Mercruiser 4.3 water in oil

    It’s odd that this would happen given that you did the winterizing all those years & never had a problem. Do you manually drain & leave dry or back fill with antifreeze? Is it possible that water got in & ran down the intake manifold? If the boat is stored with the bow up I’m wondering if failed...

    1995 Stingray 4.3L Mercruiser No Start

    Your boat is designed so that the outdrive is totally submerged when the boat is in the water. That forces water into all the passages in the outdrive. The pump must be submerged for it to prime, and even in an Alpha drive the pump is several inches above the water intakes. On a Bravo drive or...

    1995 Stingray 4.3L Mercruiser No Start

    Impellers will not suck water with a column of air in front of it. They have to be immersed in water to pull water. Even with outboards if you run in a garbage can (like we do with our little Suzuki) the water level has to be above the top of the water pump. On land use muffs as noted or else...

    Hydraulic Lifter Volvo Penta 4.3 Vortec

    Those lifters are very easy to change once the intake is off and the rocker arms & pushrods are removed. Before removing the intake set the engine so that it’s at TDC of the compression stroke of #1 cylinder and remove the distributor cap. Mark the position of the rotor on the distributor body &...

    Exhaust flappers

    I could be wrong but I think the single prop SX has thru the prop exhaust and the SX/DP has the exhaust housing on the lower unit....

    Trim/tilt rams: delete?

    Actually you didn't go wrong, you're doing it right. A good resto is expensive. I figure over 20 years I've spent approx $4500 on structural repairs, $4500 on an Imron paint job and about $2000 on a top end overhaul and new exhaust system. Do it right the first time.

    Possible hydro lock?

    Agreed with cranking the engine over with all plugs out to check for water in cyls. Water in the motor oil takes a while to show up on the dipstick remove the oil fill cap it will show up under the valve cover first. I also would dis-able the ignition system while doing this because you don’t...

    Exhaust flappers

    If you have any doubts try to measure the static water line of the boat with it in the water, you need the tops of the elbows to be 12-13” above that. I have those same OMC designed flappers in my Cobra (Volvo simply adapted the whole Cobra transom mount for the SX series) and as long as you...

    If you want a good kit, and need tech advice (forum): Cliffs High Performance Despite some negative opinions on Quadrajets because they were standard equipment on many GM cars and the majority of GM muscle cars there is a ton of information on them out there and if you have a good core & not a...

    5.7 L 574APARY STARTER PROBLEMS, please help, if possible! Thanks!!

    Yep and the faster you get the water out of the oil the better! Could be blown HGs…. Blown intake gaskets will put water in the oil but not in cylinders. Water gets in cylinders from bad head gaskets, cracked head or block or bad exhaust manifolds & elbows. If you wind up finding blown HGs from...

    1995 Four Winns Horizon 190 Trailer wheel bearings

    Those look like 6 lug hubs, probably with standard bearings. The bearings will have a # stamped on them, if they are good you can just re-pack them but I would fix the brakes. If they are drums you can just replace the backing plates (6 lug hubs will use a 12" brake assembly), if the bearings...

    Volvo penta 4.3 flooding

    Are you sure that the float is not rubbing against the float bowl somehow, bent float arm, etc?

    Engine Fire

    Either that or a gas leak from a high pressure line or injector. Either way I’d inform VP. There may be other cases & would be good for them to know.

    5.7 L 574APARY STARTER PROBLEMS, please help, if possible! Thanks!!

    I put an ARCO permenant magnet gear reduction starter in my OMC 4.3. Much better than the old direct drive starters. Light and spins the motor faster and draws less current as well. Well worth the price!

    Engine Fire

    Do you think the fire was fuel related or electrical? In any event I’d contact Volvo even if you’re out of warrantee. Hope you have insurance!
