Cummings owns Onan. Many engines before the
sale were made by Cummings. An Onan
generator came with this
boat. Cummings wants to sell you a new
engine for smaller engines. Not
overhaul parts. To
rebuild this
engine I had to go to an engine rebuilder that has access to after market
parts. Still much cheaper than
buying another engine from Cummings. Smaller diesels don't have sleeves and must be bored and fitted for new sleeves. I'd check on the availability of
overhaul parts before I bought that engine. I'll never buy another small Onan/Cummings because of the parts problem. Probably never buy a Cummings because their
service on this problem. The
service manual on my Onan
generator doesn't have even basic info on engine
maintenance, just the generator end.
