I am in the process of winterizing my boat and something came up in regards to the intake hose for the engine cooling water. My boat was re-powered 3 years ago by the PO just before I bought it so the hose in question is only 3 years old. The hose is very inflexible, heavy wall and probably wire reinforced, and is difficult to work with when removing it from the sea cock and maneuvering the end of it into a bottle or bucket of anti-freeze to winterize the engine. Is there any reason that this intake hose couldn't be of the same variety as the heater hoses used in automotive applications? They are more flexible and probably less expensive than the heavy stiff kind used in so many places on boats. I'd be interested in hearing from anyone with "hose sense".
