    Exclamation I am considering buying a boat that has a 1986 Lehman 135HP diesel engine that------

    was both sunk, pickled , got running with new starter and alternator run 550 miles ok then while refueling with engine idling at fuel dock stopped running and seized . Turns out it ran out of oil thru oil leak from a oil change system hose attached to oil sump!!! Then owner took engine out -took to shop where it was did-assembled and 2 main journals were found to be "scarred" . the all crank journals were ground down 0.010 inch and fitted with oversized bearings. Topside was inspected and passed. Engine now runs fine out o boat. QUESTION::::::::: Should tis engine be put back in boat???? OR???? Thanks, George

    George, assuming everything was checked ,the engine should be good for another 6000 hours. Have the head bolts torqued after 20 hours then normal maintenance.
