I am repowering my C&C 41. I have yanked out the GenSet (It ran well before I place the boat on the hard in Jan. 2018). Diesel powered, water cooled. You get the engine, the alternator, the associated electronics, the starting switch, a water muffler, two fuel filters (one is new and unused), heavy cables of 8-10' length for the starter), Ample Power Smart alternator regulator model SAR-12, various circuit diagrams (no, you may not ask me how to rewire this unit-I have no idea), a spare rebuilt alternator, a box of spare parts, belts, gaskets, etc. Like I stated it was running the last time I turned it over. I have done the hard, hard work of unbolting the unit. I will be here to help you lift it up and out of the boat in Canoe Cove Marina.
