WHY WINTERIZE
A LITTLE PROTECTION NOW SAVES A BIG BILL IN SPRING.
Water left in the engine and raw-water cooling system can freeze and expand. Winterizing before the first hard freeze keeps your boat ready for next season.
PROTECT YOUR ENGINE
Drain and freeze-protect the block and raw-water cooling before the first hard freeze.
PROTECT YOUR FUEL SYSTEM
Marine-grade stabilizer keeps fuel clean through months of off-season storage.
PROTECT YOUR INVESTMENT
Start next season on the water — not waiting on parts and appointments.
