I performed what I thought as being a good winterization of my boat before winter (I blew out my system with air then ran antifreeze through it). But What I did not take into consideration was the heater system. Basically the water used to cool the engine is routed through a supply and return hose to a small radiator under the console. Under the radiator a blower is mounted and that blows the air via two flex hose to two vents above and on the side of my console. When I went to run my boat last week for the first time I had an issue. As I throttled up, water started coming from under my console. More throttle, more water. So I went back to the launch and put the boat up on my trailer and starting to look around.
What I think happened is I didn't get all of the water out of the radiator and one of two things occurred, A) the radiator froze and cracked or B) The one or both of the fittings the supply and return hose connect to cracked or C) All of the above. What concerns me is come hunting season, as temperature do get below freezing, this happens again but this time I'm out in the sticks. A lot of water moves through those hoses.
So my questions is should I just replace the radiator and fittings (if so how much does a new heater radiator cost) and be more diligent at winterizing. Or what I'm thinking I should do, is saying screw the heater and connecting the supply and return hose via a double male fitting and hose clamps. I don't use the heater any way but water goes through the system regardless. My idea of connecting the supply and return seems to make sense to me as the hose are rubber and seem like would be easy to clear as gravity does most of the work, I can just help it by blowing it down and running glycol through.
Any help or additional ideas are appreciated
