Practical reference on engine flushing, hull inspection, dry-dock preparation, and step-by-step lay-up procedures before the cold season.
Articles
Three in-depth reference articles covering the main phases of seasonal boat preparation in Canadian conditions.
Engine Maintenance
How to properly flush outboard and inboard engines, apply fogging oil, change gear lube, and prevent internal corrosion before the vessel goes into storage.

Haul-Out & Storage
What to check during a haul-out inspection, how to identify osmotic blistering, through-hull fitting condition, and how to position a vessel on cradles or jackstands.

Lay-Up Checklist
A structured lay-up checklist covering antifreeze treatment for water systems, battery maintenance, interior preparation, and how to select and rig a winter cover.
Read articleWhy It Matters
Temperatures across Ontario, Quebec, and British Columbia can drop well below freezing for months at a time. Residual water left in raw-water cooling circuits, ballast tanks, bilge lines, or live wells can expand upon freezing and split components that would otherwise last decades.
A thorough winterizing process — engine flush, antifreeze treatment, drained bilge, sealed exhaust ports, and a properly supported hull — protects the vessel from the specific failure modes associated with sub-zero storage.
The articles on this site cover each phase in sequence, from the last day on the water through spring commissioning prep.
Topics Covered
Engines
Raw-Water Flushing
Outboard and sterndrive flush procedures using fresh water and fogging oil to displace salt and moisture.
Hull
Haul-Out Inspection
Osmotic blister identification, through-hull fittings, zincs, keel bolts, and bottom paint assessment.
Systems
Antifreeze Treatment
Flushing freshwater systems, head plumbing, and live wells with propylene glycol antifreeze rated for marine use.
