Stinky stuff
Gary, As far as my Jammie 33 is concerned (1980 model), there is no blower in the head compartment or hidden behind the walls. There is a vent outlet in the head, which is connected and inserted to the engine room and a vent hose there, as air from the engine compartment is pulled by the air blower in the stern compartment and vented to the outside. The system will be activated when your engine is running with the V-berth cover closed. There is a blower switch in your control panel of course. Luke Schouten
