Also known as freeze protection kits, boat lay-up gear, and off-season maintenance supplies, these products are trusted by boaters nationwide for reliable protection.
Seasonal Reminder
Start winterizing before the first freeze — usually late fall — to avoid costly damage such as cracked engine blocks or burst plumbing lines. Proper preparation saves thousands in repairs and ensures a smooth spring start-up.
Boat Winterizing Checklist
- ✔ Add fuel stabilizer to prevent clogs and ethanol issues.
- ✔ Run fogging oil through the engine and change engine oil before storage.
- ✔ Flush plumbing and protect with non-toxic antifreeze.
- ✔ Place dehumidifiers or desiccants in cabins to prevent mold and mildew.
- ✔ Cover your vessel with a boat cover or shrink wrap for full weather protection.
- ✔ Remove electronics and valuables for safe storage indoors.
Common Winterizing Mistakes to Avoid
- Skipping Antifreeze: Draining water isn’t enough — always run non-toxic antifreeze through plumbing and engines.
- Neglecting Fuel Treatment: Untreated fuel can go stale or cause ethanol damage during storage.
- Forgetting Battery Care: Always disconnect and store batteries in a dry, warm location or use a trickle charger.
- Poor Ventilation: Sealed boats without dehumidifiers often develop mold and mildew.
- Cheap Covers: Tarp substitutes often tear or let in water — invest in a marine-rated cover or shrink wrap.
