Is It possible to run a cabin heat system off this motor?

heater core type like in your truck.

I have the core fans and lines in my boat.

The motor & drive is a transplant. Merc 470 out Volvo in.

Thank you

There should be a blocked port on your engine circ pump, probably have to fab something to mate to that port. Not sure where the return line would go, can't remember if there is a plug at the back of the head to plumb to. It would be best to keep the heater core below the level of the heat exchanger.

Ayuh,... You've got the right idea, but yer flows are exactly opposite than you think...

Water flows from the block/ head, to the circulatin' water pump...
