Connecticut winters can be unforgiving to marine engines, plumbing systems and onboard equipment. For over 80 years, Petzold’s Marine Center has provided professional boat winterization in the greater Portland, CT region, helping boat owners prepare their vessels for freezing temperatures, extended storage and a smoother return to the water in spring.
Located along the Connecticut River, our Portland facility is Petzold’s full-service marine headquarters. Our experienced, factory-trained technicians winterize everything from personal watercraft and trailerable boats to larger powerboats and motor yachts.
Complete Winter Preparation for Your Boat
Winterizing a boat involves more than preparing the engine. Many vessels contain freshwater lines, pumps, heads, water heaters, generators, air-conditioning systems and other equipment that can be damaged when temperatures fall below freezing.
Our marine technicians review the configuration of each vessel before recommending service. This vessel-specific approach helps ensure that systems are not overlooked and that the work completed is appropriate for the boat’s design and equipment.
Protecting Your Boat From Freeze Damage
Water left inside an engine, hose, pump, fitting or plumbing line can freeze and expand. Even a relatively small amount of trapped water can damage components or create leaks that are not discovered until the boat is commissioned in spring.
A thorough winterization plan can help protect against cracked engine blocks, split freshwater lines, corrosion during storage, and unexpected repair expenses.

Marine Engine Winterization
Proper engine preparation is central to protecting a boat during the off-season.
The winterization process depends on the engine manufacturer, fuel type, cooling configuration and propulsion system. Our technicians stabilize fuel, drain raw-water cooling components, replace filters, inspect fluid levels and prepare batteries so your powerplant survives the cold intact.
Freshwater, Head and Plumbing-System Preparation
A boat’s plumbing system can contain water in places that are not immediately visible. Tanks, pumps, faucets, showers, heads and water heaters may all retain enough water to cause damage during a freeze.
Our certified crew traces the plumbing networks entirely, applying non-toxic marine antifreeze where needed to guarantee absolute protection.
Generator, Air-Conditioning and Auxiliary Systems
Generators and other raw-water-cooled equipment must also be included in the winterization process.
These systems can be easy to overlook because they may not be used during every trip. Identifying and preparing them before storage can help prevent hidden damage and avoid springtime delays.

An Ideal Time for Off-Season Maintenance
Winterization provides an opportunity to identify maintenance needs while the boat is already out of regular use.
Our service team inspects your vessel to catch any worn hoses, aging belts, or leaks. Addressing projects during the winter ensures your boat is completely ready when warmer weather returns.
Winterization for Boats, Yachts and Personal Watercraft
Petzold’s Marine Center can accommodate a wide range of vessels at our Portland facility.
From center consoles and bowriders to mega pontoon boats, jet skis, and motor yachts up to 70 feet — our facility handles your entire fleet.

Concierge Boat Pickup and Transportation
Your boat does not need to be located in Portland to receive service at Petzold’s Marine Center.
Concierge transportation may be available from approved homes, docks, ramps and marina locations. Our team can arrange to retrieve the boat, transport it to our Portland facility and manage its winterization and storage requirements.
Fuel and Fluid Service Before Storage
A boat may remain unused for several months during a Connecticut winter. Preparing its fuel and fluids before storage can help reduce contamination, corrosion and performance problems when the vessel is restarted.
When to Schedule Winterization
Winterization should be reserved well before the first extended freeze. Fall is the busiest period for marine service departments; planning early is especially crucial for larger vessels, multi-engine yachts, and complex onboard installations.
What Determines Winterization Pricing?
Pricing is calculated transparently based on length, number and type of engines, propulsion styles, onboard plumbing systems, generators, and chosen storage options. Let us provide a highly customized quote.
Prepare for an Easier Spring
A carefully winterized boat is easier to commission and return to service.
When winterization and storage are handled through Petzold’s Marine Center, our team can also coordinate spring preparation. Commissioning may include reconnecting seasonal systems, inspecting equipment, checking fluid levels, preparing batteries, starting engines and completing other agreed-upon services.
