Winterizing The Freshwater System - Maxum 2500SCR Owner's Manual

24 CHAPTER 6: PLUMBING
Observe the following about the freshwater system:
• Turn off the water pump when the boat is not in use or the water tank is empty.
• Inspect and clean the water filter often (located on the water pump).
• When your boat is to be left unattended for long periods of time, pump the water tank dry to prevent stored water
from becoming stagnant and distasteful.
• If the freshwater system needs to be disinfected, ask your dealer about treatments available for your boat's system.
