Oregon freeze risk for boats

Oregon freezes in short spells: Medford has about 63.9 freezing nights but only 1.0 days that stay below 32°F, and those overnight freezes are what crack a boat that was not drained.

Winterizing a boat before the Oregon freeze

  1. Run the engine on stabilized fuel so treated fuel reaches the injectors or carburetor.
  2. Drain the block and manifolds, or flush with propylene glycol antifreeze.
  3. Change engine and lower-unit oil; milky gear oil means water got in.
  4. Drain livewells, freshwater and washdown lines; antifreeze the pumps.
  5. Pull the drain plug, remove electronics and keep the battery on a maintainer.
  6. Book move-in before October 22.

Oregon boat winterization questions

When should I winterize a boat in Oregon?

NOAA's 1991-2020 median first 32°F night is November 19 at Portland and October 29 at Medford; winterize by October 15, two weeks ahead of the earlier date. By our boat rule Portland stays in the water through September and Medford through September, then 4 months of launch or haul-out follow at Portland. 38 Oregon listings offer indoor or climate-controlled space.

How many months is a boat laid up in Oregon?

3 at Portland (October to April) and 2 at Medford (October to April), plus 4 and 5 months of launch or haul-out. Those laid up months hold 4.1 of the 4.2 inches of snow Portland averages a year (98%), which is the load on a cover or carport roof. At Portland a boat is in the water from May to September (5 months), against 5 at Medford.
