Alaska freeze risk for personal watercraft

Alaska is severe-freeze country for a personal watercraft: Fairbanks averages -17.2°F on January nights and about 113.8 nights a year at or below 0°F, so full winterization is mandatory and heated space is worth pricing.

Winterizing a personal watercraft before the Alaska freeze

  1. Flush the cooling system, then run antifreeze through the flush port.
  2. Blow trapped water out of the exhaust.
  3. Stabilize a nearly full tank and run the engine.
  4. Fog the engine if the manual calls for it; grease the pump.
  5. Pull the battery to a maintainer and prop the seat open.
  6. Book move-in before September 6.
