How to or Links to Winterizing 2015 PCM Engine and Hester?

I am thinking it would be the same as my monsoon but just double checking... it has a salt water flush as well but I’m not sure that it has ever been hooked it fwiw. I have never winterized a heater before so I’ll play dumb on that.

On page 56 of the owner's manual the winterization process is described, and on page 62 it shows all the drain points (for the 350 Monsoon).  

To get the water out of the heater core, remove the heater water supply hose from the top of the intake manifold (see page 70), blow compressed air into the hose (keep it under 20 PSI) and the water will be forced into the circulation pump or engine block where it will drain out of the removed circ pump hose or block drain plugs.

It is only slightly different for the 409 or 450 Monsoon, but the concept is the same.I

If you have the salt water flush, make sure the Flush Pro housing is also drained.

You have a salt water flush... do you have a salt water package (which would include a heat exchanger with coolant in it)?

I think he is talking about the flush port mounted on the transom. I use it to run the boat in the driveway. No fake a lake.
