Anyways, I have all three...

    Johnson '72 50 HP Electric shift problem!

    I took the lower unit off to change out impeller and in the process I found that the wire that runs to the solenoid through the exhaust housing has the rubber tore and each of the individual wires somewhat exposed. The tore part is located about 3" from where it goes into the solenoid. Is this...

    How to change impeller in '72 50 HP Johnson

    50ESL72C...this is the hydro-eclectric shift, so, how hard is it to change the impeller? I have heard bad stories about the wires that go into the lower unit being compromised while seperating the lower unit from the rest of the motor. I don't want to mess this up because the hydro-electric...

    A little confused on proper carb float setting.

    I am wondering if I have set my floats correctly...so when you pull the carb off the engine and remove the bowl should the floats be hanging down at an angle and the valve closed? When you turn it upside down the float should sit parallel with the rest of the carb.

    To run the motor out of gas or not...that is the question.

    So, my dad always taught me to run the gas out of the motor when I will not be using it for the rest of the day or longer. It almost became a contest at the end of a weekend or day of fishing to see who could pull the fuel line at just the right time to have it die as you coasted onto the...
