Water Heater 33
I've got a 1980 H33 with the heater plumbed to the engine - however, the standard 2QM 15 raw water cooled engine doesn't get very hot, so while the engine running will heat the water somewhat, it doesn't get very hot, no where near as hot as when we are plugged into dockside - not much you can do about this, as the engine is designed to run much cooler than a freshwater cooled 2GMF version. THere is a good thread on this topic in the forum a month or so ago.
