I have a 1998 Jet boat with a 120hp Merc Sport jet engine. How do I drain the water from the cooling system? (freshwater use/ subzero storage)

Jason; Hook a length of hose to the fresh water inlet and dunk the other end in a 5 gal pail of anti freeze mix.Start the engine and when you see anti freeze exiting the exhaust pipe-shut down and your good to go.The jet pump it self I've not a clue.

I recently changed the nozzle on my 240 sportjet. In the process I broke the bolt that secures the steering linkage to the nozzle. Could some suggest a source for this part.
