This very well cared for Nanni 2.60HE was removed from my sailboat when it could no longer develop sufficient oil pressure. The motor does not turn. I do not know how many hours the motor has on it, but being nearly 40 years old, it is probably quite a few. It was a reliable and trustworthy engine. I considered having it rebuilt but opted for a more powerful engine. It has some spare parts with it, impeller, filters, etc.
It is located in Rumford, RI and can be picked up there or shipped at the buyer's expense (typically about $300).
