Starting motors that have sat for years....need help
 

I am going to be trying to get a couple of Fresh water cooled 502's running that have sat for three years......where should I start.......

Pull the plugs and squirt a penetrating oil in there- real well. Let it sit a day, then do it again. In a day or so, hand-turn the engines a coupe of revolutions. Then crank out as much oil as you can. Change the engine oil. Pull the pumps and look at the impellers. Check over all the fuel lines & electrics. Pump out the fuel from the tanks then fill them at least half-full- or run the engines from a remote fuel source. New plugs, filters, etc. Fire the engines & watch for obvious issues. Warm them up then run a compression test. That should do it.

I'd also take a good look at the outdrive boots.

Are these engines still in the boat or on a garage floor?

Were they pickled before they were stored?

Were the air intakes and exhaust outlets sealed shut?

Did the original owner wear briefs or boxers?

Glad to see ya still got ya sense of humor:D

Admit it...you at least smiled when you read it.
