    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...

    Lean Popping on Accleration

    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. It is there to make sure that the drive is fully engaged. I am sure someone on the site can post a picture of the switch and possibly...

    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?

    Swap an OMC 5.8 with OMC 5.7

    Some OMC flywheel housings have a dual bolt pattern for Ford or GM. Is the 5.7 a OMC version or a Merc?

    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.

    Also keep in mind that the alinement needs to be done with the boat in the water.

    Hard Start All The Time

    You need to check if the by pass circuit is the problem. Get a volt meter and check that there is at least 12 volts going to the coil while the engine is in cranking mode. On the starter solenoid there are 2 small terminals on either side of the battery cable. One side has a #10 ga. Yellow/red...

    MC-1 (aka Pre-Alpha) Gimbal Ring Replacement

    The inner original plate also needs to be compared with the male alinement extension on the Alpha outer gimbal housing. Also the 233’s exhaust down pipe‘s bolt pattern has to be checked that it mates to the Alpha housing. The Alpha inner plate mounts the steering lower which will not clear the...

    bought a kicker motor

    The new outboard will probably a 4 stroke. If so then just get a bulkhead fitting with a 1/4”npt so that the fuel line can be connected to the outboard fuel hose from a source in the boat. Summit/Jegs has them long enough to go through the transom. The rig the steering line SD suggested.

    Mercruiser Carb with 3.0 engine Alpha 1 is running a little rich. Do I go in or out with screw?

    Start with 1.5 turns out from lightly seated. Most times that is where it will be the best setting or 1/4 turn either way. Also checked in the water as dubs suggested.

    MC-1 (aka Pre-Alpha) Gimbal Ring Replacement

    I have removed that nut without drilling but it is a PITA. With a punch and a suitable hammer it can be worked loose depending of the construction of the boat. There is a 1/4” pipe plug screwed into the bottom of the shaft that has to be removed with an Allen wrench also. The seals should be...

    cobra 3.0 hesitates

    It appears that you have a Holley. If that is what you have then try this. 1.5 turns out from lightly seated with the idle mixture screws should idle correctly and with 1-1.5 turns on the idle stop screw. Any thing much more than these settings usually means it needs to be repaired.
