What should be Included in a Boat Winterization Checklist?

A comprehensive boat winterization checklist for Toronto’s climate should include the following essential steps to protect the vessel from extreme cold and freeze damage:

  1. Drain Water Systems: Remove all water from bilges, pumps, and lines using compressed air or a vacuum. Add non-toxic propylene glycol antifreeze to traps and residual areas.
  1. Stabilize the Fuel System: Fill the tank to minimize condensation and add a fuel stabilizer to prevent degradation and varnish buildup. Run the engine briefly to distribute the treated fuel.
  1. Protect the Engine: For outboards, flush with fresh water and apply fogging oil to the cylinders. For inboards, circulate marine antifreeze through the closed cooling system and fog the cylinders. Drain raw water intake lines.
  1. Electrical Maintenance: Disconnect the battery, clean the terminals with a baking soda solution, and store it in a cool, dry place or a secure facility.
  1. Hull and Deck Preparation: Clean and dry the exterior, apply a protective wax, and secure the boat with straps or blocks. Use breathable shrink-wrap or a custom cover to protect against snow and ice.
  1. Interior Care: Remove electronics, cushions, and fabrics to prevent mold and deter rodents during storage.
