Preventive Maintenance
& Winterization
WEEKLY
-
Check/clean the sea strainer
-
Check drain pan and sump pump if applicable. Sitting water in the unit’s drain pan will cause premature wear on the unit and reduce lifespan. Make sure that drains are free-flowing and that no more than ½” of water is sitting in the drain pan.
ANNUALLY
-
Visually inspect the unit for any signs of corrosion or damage.
-
Blow out drain line(s).
-
Clean return filter(s).
-
Descale seawater cooling loop.
-
Check all hose clamps and visually inspect
all hoses for kinks, cracks, or chaffing damage, replace as needed.
WINTERIZATION
WHEN THE BOAT REMAINS IN THE WATER:
For in-water storage, it’s essential to use a potable anti-freeze solution in both the water supply and discharge lines. Ensure compliance with state, local, and federal regulations before discharging antifreeze overboard.
-
Close the ball valve.
-
Disconnect the water line at the ball valve.
-
Submerge the line into a bucket of potable antifreeze.
-
Run the air conditioner until a consistent stream of antifreeze is discharged overboard.
-
Reconnect the water line at the ball valve.
WHEN THE BOAT IS OUT OF WATER
IN DRY STORAGE
When the boat is out of the water:
-
Open the seacock to allow all water to drain from the system through the thru-hull fitting.
-
Remove and empty the seawater strainer basin.
-
Loosen the screws on the pump head to facilitate water drainage from the pump and the water line between the pump and strainer.
-
Close the seacock.
WHEN RETURNING THE BOAT BACK TO THE WATER IN THE SPRING:
-
Gradually open the seacock to allow water to fill the system up to the pump’s level.
-
Tighten the pump face to establish a seal.
-
Once the pump is primed, fully open the seacock valve.
