what are you asking?
You looking for a way to plumb in a small water heater that uses engine heat? No problem. Very straightforward.

you want to tap into the engine cooling water and bathe in it?? even if fresh water cooled motor, isn't it neccessary to cool the exhaust on way out?

I belive its a small heat exchanger ..engine cooling water around a copper coil that has fresh pumped through it .. Try west marine or do a google , im sure it can be done

I would think the water would be too hot off the exhaust. A heat exchanger with a pump would work but a shower bag in the sun is not too bad either.

It wouldn't be too hot.. The regular ones come direct off of the drain cock on the block. It's cooled by mixing with the cold water from the lake. They both run thru the shower pump.

Guys, it's a simple install. A small (2 gallon) marine water heater with a coolant loop in it. On a freshwater motor, just tap into the coolant loop to the heat exchanger on the uphill side of the tstat. Run it thru the coolant loop on the water heater. Dump it back into the system on the suction side of the circ pump.
The water heater will have the proper flow diagram.
On a sea water cooled motor, you plumb it differently but it still works.
