    The issue in most cases is inside the drive, the cone clutch. This can also be caused by using the wrong gear lube

    5.7 hard start

    No and only because your tank fitting where the clear line is attached should be a antisiphon valve. The valve is a safety requirement and also helps keep fuel in the line

    Maybe my turn for new boat time

    OK, which one? If I get a 50CC install manual says it "should" give me 6.5 LtoL. But can I get 4 to 5 with another, but then the question will it work? Will steering be to heavy? I don't know but trying to research which would be correct I don't even know which one I have installed now

    Audio warning system on 2003 Mercruiser 5.0

    Unplug the lube bottle, oil pressure switch and temp switch then see which one is turning it on. The switches just turn ON the alarm You replaced the oil switch but maybe you actually have low oil pressure or something else. If the oil switch does turn the alarm OFF, then connect a mechanical...

    Riser elbow & intermediate elbow

    Very likely but those parts may need to be longer with using a riser. Most Mercs I've seen only use one size of boots, so something have to be added to attach to exhaust Y pipe

    5.0l EFI won't start after sitting hot for a while

    Welcome Sounds like vapor lock. After stopping the heat soaks into the fuel system and boils the fuel. The excess fuel gets pushed into the filter and leaves the vapor. When motor cools down the fuel returns MPI motors have a easier quick fix with having a schrader valve that can be pressed...

    8.1 GXI-J Cranks but No Start w/ Diacom Logs

    If it's going to take a bit of time before motor is getting work, I would have the oil changed with some cheap oil. This is just to get some more of the water out. Change and start for a minute then shut down With water in the oil the motor will need to be taken a part until the area is...

    5.0 GXI C no start

    The distributor you have is a HSV and uses what most call a crap cap. They go out without warning and cause all kinds of problems. It's best to keep a spare on board. Would suggest replacing it and if it doesn't help at least it's been ruled out and keep as spare
