Professional boat winterization services for Novi, MI
Michigan winters are hard on boats... freezing temperatures, ice formation, and moisture can cause thousands of dollars in engine damage if your boat isn't properly winterized. Since 2011, we've been protecting boats for Novi residents with comprehensive winterization services that follow manufacturer specifications and protect your investment through the off-season.
Whether you have an outboard, inboard, or stern drive engine, you NEED proper winterization to protect your boat, jetski, seadoo, etc.
- Water left in your cooling system can freeze and crack engine blocks
- Untreated fuel can gum up carburetors and fuel systems
- Moisture can corrode electrical connections and engine components
Our winterization service addresses all of these concerns with thorough, professional preparation that gives you peace of mind all winter long.
Outboard engine winterization
Outboard motors require specific winterization steps to prevent freeze damage and corrosion. Our outboard winterization service includes:
Fuel system protection
We add fuel stabilizer to prevent fuel degradation during storage. Untreated fuel breaks down over time and can clog fuel lines, filters, and carburetors. Stabilizer keeps your fuel fresh and your fuel system clean.
Cooling system service
We completely drain the cooling system and fill it with marine-grade antifreeze. Any water left in the cooling passages can freeze and crack your engine block, which is an expensive repair. We ensure every drop of water is removed and replaced with antifreeze protection.
Engine fogging
We fog the engine with protective oil that coats internal components and prevents corrosion during storage. This protects cylinder walls, pistons, and other internal parts from moisture and rust.
Carburetor drainage
For carbureted outboards, we drain all carburetors to prevent fuel from gumming up the jets and passages. This is a critical step that many DIY winterizations miss, and it prevents frustrating carburetor problems in the spring.
Battery disconnection
We disconnect the battery to prevent parasitic drain during storage. A dead battery in spring is inconvenient, and leaving batteries connected can also create potential electrical issues.
Exterior protection
We spray the exterior of the engine with protective lubricant to prevent corrosion and rust on metal surfaces exposed to moisture during storage.
Lubrication
We grease all applicable fittings to protect moving parts and prevent corrosion on pivot points, steering components, and other mechanical systems.
Inboard and Stern Drive Winterization
Inboard and stern drive engines have similar, but different winterization requirements than outboards. Our service protects these systems with manufacturer-recommended procedures.
We stabilize the fuel system, drain and protect the cooling system with antifreeze, fog the engine to prevent internal corrosion, and disconnect batteries. For stern drives, we also service the outdrive components and ensure all water is removed from the drive unit.
Inboard engines are particularly vulnerable to freeze damage because of their complex cooling systems. We ensure every cooling passage is properly drained and protected with antifreeze to prevent catastrophic engine damage.
Engine oil and filter changes
While your boat is being winterized, it's the PERFECT time to change the engine oil and filter. The reason we do this is because old oil contains combustion byproducts, acids, and moisture that can corrode engine internals during storage. Fresh oil provides better protection and ensures your engine is ready to run when spring arrives.
We use quality marine-grade engine oil and OEM or equivalent filters. Oil changes during winterization mean one less thing to worry about during spring preparation, and it's better for your engine to store it with fresh, clean oil rather than contaminated oil sitting in the crankcase all winter.
Lower unit service
The lower unit (or outdrive on stern drives) contains critical gears that need proper lubrication. We drain the old lower unit lubricant and inspect it for signs of water intrusion or metal particles that could indicate gear damage. Then we refill with fresh synthetic gear lube that protects your gears throughout storage and into the next season.
Water in the lower unit can cause serious gear damage, especially during freezing temperatures. This service catches potential problems early and ensures your lower unit is properly protected.
Professional shrink wrap service
Winterization protects your engine and systems, but shrink wrap protects the entire boat. We offer professional marine shrink wrap priced per linear foot. Our experienced team uses proper techniques to create a tight, weather-resistant seal while ensuring adequate ventilation to prevent moisture buildup and mold growth inside your boat.

Shrink wrap keeps snow, ice, rain, and debris off your boat throughout the winter. It's especially important if your boat is stored outdoors. Learn more about our boat storage options in Novi, MI.
Complete detailing services
If you want your boat looking its best when you bring it out of storage, we offer full interior and exterior detailing services. We can clean, polish, and protect your boat's surfaces so it's showroom-ready for the spring season. Detailing before storage also helps protect surfaces from degradation during the off-season.

Spring preparation service
Winterization protects your boat during storage, but spring preparation gets it ready for the water. Our spring prep service includes:
- Pulling your boat from storage
- Connecting and charging the battery
- Checking all fluid levels
- Starting the engine and verifying operation
- Testing the water pump
- Preparing the boat for launch
This comprehensive service means you skip the frustration of troubleshooting a boat that's been sitting all winter. We verify everything is working properly before you head to the launch, so your first day on the water is enjoyable rather than stressful.
