[C320-list] Water Pump Hose & Winterizing

[sailorlew at aol.com]

The reason that you need wire reinforced hose for this application is because it is being subjected to suction pressure from the water pump & can possibly collapse causing overheating without the wire reinforcement. The hose from the pump to the heat exchanger does not require wire reinforcing but I would not use clear hose for this application.

  I was inspecting my water hose that connects the thru-hull with the raw
water filter. It was badly dried & cracked and will be replaced now. It is
an extremely heavy hose with wire reinforcement. Is all that really
necessary? Can I replace it with heavy duty clear, reinforced hose?
  On my last boat, I would open the filter cover and pour anti-freeze into
it while running the engine until the exhaust water ran pink. Since the raw
water filter opens from the bottom, how do you run anti-freeze through the
system?
  Thanks.
