    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...

    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...

    Mercruiser 4.3 oil gauge mystery

    How did you test them? Would think you need to apply different pressures and see if the ohms change , dont know the ohm range off hand but usually if you ground tge sensor wire gauge should peg one way or other

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    If there is fuel present in the tube your mechanical fuel pump needs replacement. as mentioned this will be pushing fuel from a ruptured fuel pump diaphragm into the carb bores… better than the fuel going into the bilge though. Get a marine replacement pump and you should be good. may be other...

    If you think the fuel lines look bad from the outside I would replace them could be degraded on inside? Can you rig up a fuel pressure gauge to watch while running

    Mercruiser 4.3 oil gauge mystery

    I think the alarm switch (which sounds on start) and switch for fuel pump are two different switches.

    Mercruiser 5.0LX Rochester 4MV carburetor over fueling. ESN OF066511

    Agreed- had a float with a small split on it couldn't tell it was leaking ... To OP -These could be your issues Float being gas logged or hanging up needle and seat too high fuel pressure I assume you have a mechanical fuel pump - there should be a clear tube coming of it and going to carb...

    Dam it! Wont Idle

    Heres a video on it or the first one in a series showing rebuild. usually if idle circuit is plugged it will idle low or wont idle… make sure the linakge is not hanging up. I would disconnect the throttle linakge and make sure throttle plates are returning against the idle speed screw, look...
