Diesel, sitting

2 posts in this topic

I have a Yanmar diesel that has been sitting for 10 years. It is in the boat  and I assume it was running when the boat was tied up to the pier. But I also suspect that it simply had the thru-hulls closed and no other storage steps taken.

My question is what is the best way to begin resurrecting it? As of yet I have not tried to turn the crank.

I'm not a diesel mechanic but have run and maintained them for years.  I would replace all the fuel filters first.  Be sure to fill the filters with fuel when installing.  Remove the air filter and spray the air chamber with WD-40 a good 3 second spray, replace the airfilter and start the engine.  It will run on WD and that will lube the cylinders a bit.  Maybe someone else will chime in with something else to do also.
