I have a 1977 Johnson 70hp, I no longer need. She is complete, crank gets sticky after sitting for a week, squirted oil in the spark plug holes, frees up for a while then sticky again. Probally crank bearings getting tight.
Anyway, is there much of a market if I was to part thi moror out... carbs,starter, etc? Thanks for the info and God Bless our brave fightin' service people...

Re: Part out or sell whole?

i would do a decarb on it, see if that frees it up.

Decarb, take a can of seafoam put 3/4 of it in the gas tank, with only 1 gallon of premixed gas. put the rest in a spray bottle. start the engine, and let it come up to temperature. then remove plugs, and them some real good shot of seafoam into the cylinders, replace plugs, let sit 15 minutes. restart, and spray the rest of the seafoam into the carbs, so the the motor almost stalls, wait and repeat until the seafoam is gone.then take for a wide open spin. then put in new plugs, ad premixed gas to the tank, and take it for a wide open throttle spin. it is going to smoke like a house on fire, during this process.

afterwards compression.recheck

there is a big demand for running 70's. also make sure there is not water getting into the cylinders.
