    Why not a gearbox

    One for the JB's of the world... Would there be any benefit of having a multi-speed gearbox on an outboard to keep down the revs, whilst keeping the prop spinning at the required speed ?

    6 HP Suzuki won't idle

    I have a 1986 6hp 2 cyl Suzuki that is not started very often and is used as an emergency Auxiliary motor. When I do run it @ once month in a barrel, it will run OK and then just stall. If I keep increasing the revs or use the choke, it will keep running, but leave it to idle and it quits. I...

    50 HP 1979 Merc shift shaft

    Coil Grounding 50 Merc 79 coil pack

    I have a corroded ground wire on the 3rd coil that goes to the switchbox ground. It looks like an ordinary wire but had what looked like a heat resistant rubber section at the coil end. It is feasable to just replace it with about the same gauge auto wire, being only an earth ? Or is there...

    Noisy operation 79 Merc

    My 1979-80 50 hp Merc runs fine, but when you put your ear right up to the cowling, it is rather noisy. Sounds like tappet noise on a car engine. Almost like diesel engine sounds. If I try to shake the flywheel, there is very little play there (Nothing too drastic). Is this noise normal for a...

    Suzuki in Barrel

    To those who flush your little motors in a barrel or trough. Don't be alarmed if it doesn't run quite right, smokes alot and leaves oil floating on the water.<br />My 86 DT-6 Auxiliary has always run poorly in a barrel, but yesterday when I needed it out on the water, she never missed a beat. No...
