Pennsylvania freeze risk for personal watercraft

Pennsylvania is hard-freeze country: Pittsburgh logs about 113.6 nights at or below 32°F and 31.7 days that never thaw, enough to freeze any water left in the exhaust, cooling passages and pump housing.

Winterizing a personal watercraft before the Pennsylvania 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 October 16.
