    Are drive shafts interchangeable before 1992 and after 1993 for 9.9's / 15's

    It is not very hard to make the long shaft shorter. Just take it to a tool and die worker with a lathe and tell him how long you want it. It should not take very long.

    The electric start kit has a rectifier which will slowly charge your battery if you run it at a decent rpm .

    JOHNSON 55 HP TILT PIN QUESTION

    During the 36 years that that engine has been around it may well be that the bracket has been changed out for a non original one

    Carb hoses on 1990 OMC 3.0

    The hose coming from the pcv valve should go to the flame arrestor. The one from the bottom of the fuel pump should go to the bottom hole on the carburetor and the second one from the valve cover should not be there. That hole should have a cap on it and it is there so you can add or change oil...

    1986 Johnson 9.9

    It often happens that a spider or other insect builds a little home in the rubber hose that the water is supposed to squirt out of. Use a piece of wire to make sure that the outlet is not clogged. That often solves the problem

    1978 Evinrude, 35 HP starter will not spin the fly wheel

    It never hurts to clean stuff up, This could be a case of plugs that screw in way too deep or simply a battery that is too weak to deal with the compression that this engine produces. A good fact that was mentioned is that without the plugs , it turns over just fine. That to me is a sign that a...

    cooling johnson / evinrude 9.9 /15 fourstroke 1998

    That sounds like you were repeating the same mistake every time you changed an impeller. It is time for a step by step with the manual in hand.

    cooling johnson / evinrude 9.9 /15 fourstroke 1998

    What you just described sounds like a piece of dirt or rubber clogging a cooling passage in the block. possibly next to the thermostat, or a faulty thermostat. Clean the passages (reverse flow with a garden hose) and check the thermostat.

    1999 15 hp runs great but is very hard to start. I just changed the water pump. But im sure thats not the problem

    Sounds like a choke that does not function, or the fuel not getting to the carb when you pump it. Check the fuel connections.

    Starcraft Islander 221v fuel consumption.

    That sound like a 50 mile 12 hour trip. That gives me an idea of what to expect. I was worried that a ride from Oswego Harbor to the northern dunes would bankrupt me, but its not that bad.

    Starcraft Islander 221v fuel consumption.

    What sort of fuel economy can I expect with this Islander running on a completely rebuilt 1989 4.3 liter OMC Cobra (Michigan Motorz 2022 ). I am used to a 140 horse 4 cylinder mercruiser which I am told only "sips" fuel. I don't race all over the place, but I am curious to know what to expect...

    1970 4 hp Evinrude stops suddenly

    I have a crazy question,but it may be the key to your problem. When you slide the impeller down the driveshaft there is a small piece of metal that seats onto the driveshaft . It locks the impeller in place. Without it, just a tiny bit of water will make it to the engine and the engine will...

    est ignition on a 1989 4.3 liter cobra.

    Working on this project I find myself going back and forth between the 4.3 liter wiring diagram and the 3 liter HO wiring diagram

    est ignition on a 1989 4.3 liter cobra.

    For now I plan to completely bypass the ESA system and wire it exactly as a mercruiser. This means that I will connect a +wire to the shift interrupter while the black wire coming from the distributor will be connected on the other side and when shifting ,this will send power to the distributor...

    1970 4 hp Evinrude stops suddenly

    Did you check the pipe that goes from the pump into the engine block for blockage? Did you make sure that the rubber boot at the block is present ? and did you make sure that the water cooling copper tube is fully inserted both in the pump and the block? Last but not least. Did you make sure...

    est ignition on a 1989 4.3 liter cobra.

    I unwrapped the insulation around the wires and found out that this thing is hooked into the + orange wire that goes from the alternator to the battery and the other wire coming out goes to a ground. It is definitely after market but I am at a loss as to what is is for. Maybe a diode?
