Pump out the head (dockside discharge), and be
sure the holding tank is empty. Flush the head
holding tank with soap, water and a deodorizer
(e.g., Lysol Liquid™). Add more water if neces-
sary. Have the cleaning solution pumped out.
4. Be sure all the water is completely drained from
the fresh water system. Disconnect all hoses,
check valves, etc. and blow all the water from the

tenance in this manual for information on winter-
izing the water system.
Have the fuel tank either full or completely empty.

7. Remove the batteries and store in a cool place.
Clean the batteries using clear, clean water. Be
sure the battery has sufﬁcient water and clean
terminals. Keep the batteries charged throughout
the storage period. DO NOT store the batteries
on a concrete ﬂoor or other damp or conductive
Winterize the engine and drive systems as recom-
mended in the engine owner’s manual (applies
