    Ready to ride, summer projects?

    the adapter plate stays in between the exhaust manifold and elbow. I took it off and plugged it so i could use it on my GTO as well. I think the boat is pretty dialed in (a tad rich) so i dont know if put it on. it sat in a box all winter i was just gonna reinstall it on the gto now that the...

    Mercruiser 260 overheating please help

    First place to start is water pump impeller , if an alpha drive will be in the drive need to split haves. If a bravo drive it will be belt driven on the front of engine. also check exhaust manifolds and risers for plugging and thermostat while you are in there

    Ready to ride, summer projects?

    pretty sure that is the oem manifold and made by GM. That is the only cast iron 4 bbl manifolds I have seen for the 4.3 Edlebrock manifold also seems to be single plane with a partial divider as well. Both like like each side of the carb is essentially feeding 3 cylinders I think until you...

    trouble getting reverse.

    If you are running a engine driven sea water pump with a through hull fitting for water pick up, then yes you want the hose to be cut in bellows area so impeller in drive is pushing water through the drive and out the cut hose to cool it. Engine driven pump will cool the engine separately.

    Swap an OMC 5.8 with OMC 5.7

    Yes I believe so. Even if the bolt holes need to be filled and re-drilled the transom cutout if the same. @Bondo can you confirm

    trouble getting reverse.

    When you run a belt driven raw water pump on an alpha , you are supposed to cut the water supply hose in the bellows area. The drive impeller still needs to be maintained to push water through the drive to cool it. Usually this is done if closed cooling is added.

    Swap an OMC 5.8 with OMC 5.7

    Cobra and Merc Alpha and Bravo use the same transom cutout. OMC was so far behind Merc in sales they wanted the cobra drive to be easy for boat manufacturers to use interchangeably with merc so they used the same hole. If you have the Chevy 5.7 complete it will be easier but hard to say if all...

    1992 Bayliner 4.3

    In addition to Teds comments - when you remove the plugs it should easily turn by starter or by hand. If it is locked up after removing plugs, pull the drive as it could be an issue with drive, gimbal bearing, or u joints as well. If you have to pull the drive an it is still locked up then...

    Correcting gear ratio with prop size

    As others have mentioned what is your current WOT rpm ? What mph are you getting on GPS and what is the current prop? Is it a basic Aluminum black max or similar ? Is you engine in a good state of tune - no performance issues? I have a 21 ft sea ray with a 5.0, I have a 4 bbl carb vs your efi...

    How do I see if my jet ski is cooling itself

    My 2004 sea doo has a pee hole on side of hull below your left foot. Water comes out a bit at idle and hard and fast when at speed. This means cooling water is circulating. If your wear ring is worn the amount getting pushed out will be less. You may have a blockage somewhere. i belive this port...

    Engine was Full of Clear Fluid when I drained oil

    Would put a core plug in and pressure test the cooling system, but unless the water got in the crank case another way its heavily pointing to a cracked block. look at block just below the head on manifold side bet you will see a crack there and on manifold as well. if rest of boat is in good...

    Engine was Full of Clear Fluid when I drained oil

    If a freeze plug was pushed out it likely froze from lack of winterization

    Lost gearage?

    I thinking it’s a typo and he swapped a gen ONE bell housing and gen ONE drive on which bondo thought he could do with a little head scratching Be interested to see how the bellows worked out as gen one and two are diff drive bellows

    Serial number

    The US single flare and double flare are completely different fittings, same with metric bubble flare. I would use the marine fuel hose from amazon you mentioned .

    Mercruiser 4.3 oil gauge mystery

    A switch and a sender are two different things. A switch like the oil pressure switch used for the alarm circuit will be open when the pressure is above the set point ( 4 or 7 psi). When it is below the setpoint like when starting or ignition is keyed on but engine is not running, the switch...
