b. Place a bucket under the washdown fitting to
catch the antifreeze, which can be reused.
c. Open the washdown faucet. When a steady
stream of antifreeze flows from it, close the
faucet.
7. Pour one or two quarts of nontoxic antifreeze into
each shower drain until the shower sump pumps
turn ON.
8. Pour a quart of nontoxic antifreeze into each sink
drain.
9. Winterize the engine heat exchanger system. When
the boat’s engines are running, this system, rather
than the electric water heater, heats fresh water to
provide hot water.
a. Locate the 5/8" heater hose that runs from the
port engine to the water heater and back to the
engine.
b. Disconnect the heater hose in both places where
it connects to the engine.
c. Drain all water from the hose.
d. Pour antifreeze into the hose.
Preparing the System for Use Again
When you remove your boat from storage and prepare to
use it again, flush the entire fresh water system with
fresh water. Nontoxic antifreeze is colored, so the water
system is adequately flushed when uncolored water
flows from all of the faucets and shower heads.
Before performing this procedure on the optional raw
water washdown, your boat should be pulled from the
water.
1. Locate and close the thru-hull valve that supplies
the raw water washdown pump with seawater.
2. Disconnect the end of the hose that is attached to
the thru-hull valve.
