    VP 280 Engine Alignment

    If you are in doubt then try to hang the front of the engine with the engine hoist. Or a small jack under the engine. Then loosen the mounts and raise and lower the engine easily to set the alignment. This saves a lot of time instead of turning the nuts to set the alignment.

    VP 280 Engine Alignment

    Just bolt the whole thing together Into the transom plate. Then with either the diameter of a pencil eraser or similar item use that as a gauge around the outer perimeter of the mounting collar to the transom plate. That will properly set the alignment.

    2007 Volvo Penta 5.0gxi - no compression in # 4 cylinder

    If you are handy with the tools just pull the head in question. Most likely the piston is not damaged enough to cause any problems. The head can be brought to any engine machine shop who can check if the head is still usable or not. You may have a manifold with an internal leak so plan on a...

    Sometimes spark plugs will act like that. You may have an exhaust manifold that is leaking internally. Before you start the engine after it has sat for some time remove the spark plugs and look for moisture.

    Mercruiser 383 Mag Stroker MPFI Bogs Over 3000 rpm

    There is a switch on the shift linkage plate that prevents the engine from going over a certain speed if the shift is in neutral, sometimes that is the problem.

    Should I grease upper gear case housing before install?

    I always would slightly spread the split ring open to make sure it is holding the shims in place. If the split ring was first it would allow the shims to fall and get damaged while installing the driveshaft.

    888 running cold

    The stainless plates are supposed to have a small bleed hole to keep air pockets from collecting in the manifolds. Just look closely at the mounting area and if a stainless plate is there, if so then there will be 2 gaskets on either side of the plate. If my memory is correct the bleed hole in...

    888 running cold

    If the by pass hole in the thermostat housing has been enlarged that could be the reason for running too cold. There are several advertised on google search. Do you know if the correct stainless plates are between the risers and manifold bodies?

    Starter won’t engage flywheel

    The only other thing that can be the problem would be the flywheel ring gear has lost its tension on the flywheel. Very rare but it could be the problem. Remove the starter and check if the ring is loose.

    Swap an OMC 5.8 with OMC 5.7

    In that case then it should be a slam dunk. Especially if the GM engine has the electrical. The Ford probably was fuel injected, if not all the better as you will end up with extra electrical components. What was wrong with the Ford engine?

    Mercruiser 3.0 starter

    Most times when the starter spins but does not engage there is a rust build up on the shaft which stops the gear from moving toward the flywheel. The solenoid lever is compressing the spring that normally pushes the drive to the flywheel. Sometimes just a strip of sand paper with WD 40 or...

    5.0 Gxi-ce 270-r misfires cyl 4&7 at full throttle

    Check if the fuel rails are stainless of plain steel with a magnet. A shop owner friend told me about a Volvo that had plain steel rails that had some rust inside which was getting on the screens of the injectors which caused some problems.
