North Dakota freeze risk for boats

North Dakota is severe-freeze country for a boat: Fargo averages 0.2°F on January nights and about 41.7 nights a year at or below 0°F, so full winterization is mandatory and heated space is worth pricing.

Winterizing a boat before the North Dakota 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 September 20.
