I think the water heater was standard equipment ..
on the LE and you will probably find that the hot water lines are already installed ... On mine, with the Universal engine, the heater was removed by PO, and the two lines from the motor are just coupled together and sitting at the bottom of the lazerette. If I remember right the fresh engine hot water comes out of the engine ... flows through the water heater and then into the heat exchanger. There is a 110 ac double plug right there as well. You can just plug the unit in. But then there also should be another coupled loop that came from the water tank to the hot water line for the sinks. maybe a T off the cold water line.Those water heaters are pretty standard and used in a lot of boats right off the shelf. If I had the space I would mount it on the Wooden bulkhead behind the galley ... but that's where I put the racor, fuel pump, and the battery switch in a revamp a few years ago. Vic "Seven" #622
