End-of-Summer Maintenance: Protecting Your Boat, RV and Personal Watercraft

End-of-Summer Maintenance: Protecting Your Boat, RV and Personal Watercraft

As summer winds down and fall approaches, recreational routines begin to change. Boats, personal watercraft, RVs and other recreational vehicles may spend less time on the road or water and more time in storage.

Parking these high-value recreational assets for the cooler months involves more than simply finding an open spot in a driveway or rental lot. Proper seasonal preparation and strategic policy management prevent hidden deterioration, structural damage, and costly repair bills when spring arrives.

1. Watercraft and Jet Ski Storage Protocols

If temperatures fall below freezing, water left inside certain boat or PWC systems can expand and cause serious damage to engines, cooling systems, plumbing and other components. Water trapped inside internal systems expands during cold snaps, causing cracks in engine blocks and cooling lines.

  • Drain the System Completely: Flush out the cooling system according to the manufacturer specifications. Clear any remaining water from livewells, bilge pumps, and internal plumbing.
  • Stabilize the Fuel: Liquid fuel degrades when left stationary for months, turning into a gummy residue that clogs lines and fuel injectors. If recommended for your equipment, adding the appropriate fuel stabilizer before storage can help protect fuel quality during extended periods of non-use. Follow the manufacturer's recommendations for fuel and storage preparation.
  • Clean and Protect the Exterior: Algae, lake residue, dirt and grime can remain on the hull after a summer of use. Clean the exterior before storage and follow the manufacturer's recommendations for protecting the finish.

2. Motorhome and RV Systems Checklist

Recreational vehicles function as mobile homes, meaning they contain multiple interconnected utility systems requiring winterization.

  • Plumbing Protection: Drain the freshwater tank, black water tank, and grey water tank completely. Running non-toxic recreational vehicle antifreeze through the water lines protects the pipes from freezing and bursting.
  • Pest Mitigation: Mice and insects seek warm shelter as weather turns cold. Remove food and thoroughly clean storage areas. Inspect the RV for possible pest entry points and seal appropriate openings without blocking required vents or appliance ventilation.
  • Tire Care During Storage: Leaving heavy motorhomes stationary on bare ground for months creates flat spots in tire rubber. Park the vehicle on protective blocks or level jacks and apply UV-resistant covers to shield the sidewalls from dry rot.

3. Protect Batteries and Electrical Systems

Batteries can slowly lose their charge when a boat, RV or recreational vehicle sits unused for several months. A weak or dead battery may not work when you are ready to use the vehicle again and can be more vulnerable to damage during freezing weather.

  • Disconnect the Battery: Follow the manufacturer's instructions for disconnecting the battery or using the vehicle's battery-disconnect switch. This can help prevent small electrical systems from slowly draining the battery while the vehicle is stored.
  • Keep the Battery Charged: Depending on the type of battery, a maintenance charger may help keep it properly charged during storage. Follow the battery manufacturer's recommendations or remove the battery and store it properly if recommended.
  • Check Wires and Connections: Before storing the vehicle, look for loose connections, damaged wires or signs of wear. Finding a small problem now may help prevent a bigger electrical problem next season.

4. Reviewing Insurance Needs During the Off-Season

A common mistake involves dropping insurance coverage entirely during months when a boat or motorhome sits unused. While a vehicle is not moving on highways or waterways, major risks remain active in a storage yard or garage.

  • Physical Damage Coverage Matters: Fire, falling tree branches, vandalism, and structural collapse of a storage barn are risks that continue through winter. Retaining comprehensive insurance shields the asset against these non-collision events.
  • Lay-Up Periods: Specialized insurance carriers offer policies with designated "lay-up" periods. This structure reduces premium costs during months of non-use while maintaining essential storage protections intact. It would be beneficial to contact your local Independent Insurance Agent to discuss if this is an option for your situation.
  • Don't Forget the Trailer: Ask how your boat or PWC trailer is insured. A trailer may need to be specifically listed or included on the watercraft policy for physical-damage coverage. Auto insurance may provide certain liability protection while towing, but that does not necessarily mean damage to the trailer itself is covered.
  • Understand Freeze and Winterization Requirements: Don't assume insurance will cover damage caused by freezing. Some policies may exclude freeze damage or require specific winterization procedures before coverage applies. Review your policy and follow the manufacturer's recommendations before temperatures drop.

The Bottom Line: Proper seasonal storage can help protect your boat, RV or personal watercraft and make getting back on the road or water easier when warmer weather returns. Follow the manufacturer's maintenance and winterization recommendations, and don't overlook your insurance during the off-season. An independent insurance agent can help you understand how your current coverage works during storage and review options from the insurance companies they represent.

Insurance is not a substitute for proper maintenance but understanding both can help protect an investment you've worked hard to enjoy.

Frequently Asked Questions

Do I need to winterize a boat or personal watercraft in Georgia?

It may be necessary even in Georgia. Northeast Georgia can experience temperatures below freezing, and water left inside certain engine, plumbing or cooling components can cause expensive damage. Follow the manufacturer's winterization instructions for your specific boat or personal watercraft.

Should I cancel boat or RV insurance while it is in storage?

Usually, canceling coverage simply because an RV, boat or PWC isn't being used deserves careful consideration. Theft, fire, vandalism, falling objects and weather-related losses can still occur during storage. Before changing coverage, talk with your insurance agent about what protection would remain and what you could be giving up.

Does insurance cover freeze damage to a boat or RV?

It depends on the policy and the cause of the damage. Policies may contain exclusions, maintenance requirements or winterization conditions that affect coverage for freezing. Insurance should not be considered a substitute for properly preparing the vehicle or watercraft for cold weather.

What is a boat insurance lay-up period?

A lay-up period is a provision found in some watercraft policies that designates a period when the boat is stored and not being used. Coverage, restrictions and any premium savings vary by insurance company and policy, so owners should understand the terms before assuming they can use the boat during that period.

Is my boat or PWC trailer automatically insured?

Not necessarily. A trailer may need to be specifically listed or included on the watercraft policy for physical-damage coverage. Your auto policy may provide certain liability protection while you are towing a trailer, but that does not necessarily cover damage to the trailer itself.

What should I review before storing an RV, boat or PWC for the season?

Review the manufacturer's winterization instructions, plumbing and cooling systems, fuel, batteries, tires, storage location and security precautions. It is also a good time to review your insurance policy to understand how the recreational vehicle or watercraft is protected while it is not being used.

If your recreational vehicle, boat or personal watercraft will be stored for several months, a licensed independent insurance agent can help you review your current coverage and available options before making seasonal changes.
