Owning a Sea Hunt boat means enjoying a versatile and high-performing vessel for fishing, cruising, and watersports. To keep your boat in peak condition throughout the year, it’s essential to follow a seasonal maintenance schedule, including winterizing before cold weather sets in and preparing for summer to ensure a worry-free boating season.

This guide will provide you with detailed steps for winterizing your Sea Hunt boat, seasonal care tips, and how to prepare your boat for summer use, covering everything from engine care to hull maintenance and battery storage.

Why Seasonal Care Is Important for Your Sea Hunt Boat

Seasonal maintenance ensures your boat is protected from harsh weather conditions and ready for peak performance when boating season returns. Whether you’re storing your boat for the winter or getting it ready for summer, proper care helps:

✅ Prevent costly repairs
✅ Protect your engine and systems from freezing temperatures
✅ Maintain the boat’s appearance and value
✅ Ensure safe and reliable performance on the water

🌨️ Winterizing Your Sea Hunt Boat: Protecting Your Boat During the Off-Season

Winterizing your boat is essential if you live in an area with freezing temperatures. Failing to properly winterize can lead to serious engine damage, cracked hoses, and corroded components.

Step 1: Clean and Inspect Your Boat

Before winterizing, give your Sea Hunt boat a thorough cleaning to remove salt, dirt, and debris that can cause damage during storage.

• Wash the hull and deck with marine soap.
• Remove any stains from the gel coat using a boat-specific cleaner.
• Clean the upholstery with vinyl-safe cleaner to prevent mold and mildew.

Step 2: Flush and Winterize the Engine (Yamaha Outboards)

The most critical step in winterizing your Sea Hunt boat is protecting your Yamaha outboard engine.

1. Flush the Cooling System
   • Connect a freshwater hose to the engine’s flushing port and run freshwater through the cooling system for 10-15 minutes to remove salt and debris.
2. Stabilize the Fuel System
   • Add Yamaha Fuel Stabilizer to the fuel tank to prevent fuel degradation during storage.
   • Run the engine for a few minutes to circulate the stabilizer through the fuel lines.
3. Change Engine Oil and Gear Oil
   • Drain and replace the engine oil with Yamaha-approved four-stroke oil.
   • Change the gear oil in the lower unit to prevent water intrusion and gear damage.
4. Fog the Engine
   • Spray fogging oil into the air intake or spark plug holes to coat the engine’s internal components and prevent corrosion.
5. Disconnect the Battery
   • Remove the battery and store it in a dry, cool place.
   • Trickle charge the battery periodically during storage to maintain its health.

Step 3: Drain and Protect the Water Systems

If your Sea Hunt boat has freshwater tanks, livewells, or a toilet system, it’s important to drain and winterize these systems to prevent freezing and damage.

• Drain all freshwater tanks and lines.
• Flush livewells and baitwells with freshwater and leave the drains open.
• Use non-toxic marine antifreeze in toilet systems to protect them from freezing.

Step 4: Protect the Boat’s Interior and Exterior

• Remove cushions, life jackets, and electronics to prevent mold and mildew.
• Store them in a dry, climate-controlled area.
• Cover the boat with a high-quality boat cover to protect it from dust, debris, and moisture.

🌞 Preparing Your Sea Hunt Boat for Summer: Get Ready for the Water

As the weather warms up, it’s time to prepare your boat for the summer season. Proper preparation ensures your Sea Hunt boat is ready for smooth and safe performance on the water.

Step 1: Inspect and Clean the Boat

1. Remove the Cover and Check for Damage
   • Inspect the hull and deck for any cracks, chips, or damage that may have occurred during storage.
2. Wash the Exterior
   • Use marine soap to wash the hull and deck.
   • Apply wax to the gel coat to protect it from UV rays and saltwater exposure.
3. Check the Upholstery
   • Clean the seats and cushions with a vinyl cleaner and apply UV protectant to prevent fading and cracking.

Step 2: Reinstall the Battery and Electrical Systems

1. Reconnect the Battery
   • Clean the battery terminals and apply dielectric grease to prevent corrosion.
   • Reinstall the battery and ensure it holds a charge.
2. Test All Electrical Components
   • Check the lights, bilge pumps, and electronics to ensure they are working properly.

Step 3: Inspect and Service the Yamaha Engine

1. Check the Engine Oil and Gear Oil
   • Ensure the engine oil is fresh and at the correct level.
   • Check the gear oil for milky discoloration, which may indicate water intrusion.
2. Inspect the Propeller
   • Remove the propeller to check for dents or damage.
   • Grease the prop shaft before reinstalling the propeller.
3. Replace Spark Plugs
   • Check the spark plugs for wear or corrosion and replace if necessary.
4. Check the Water Pump and Impeller
   • Inspect the impeller for wear and replace it if necessary to ensure the cooling system functions properly.

Step 4: Inspect Safety Gear and Registration

1. Check Safety Equipment
   • Ensure you have the required life jackets, flares, fire extinguisher, first aid kit, and emergency whistle on board.
2. Check Boat Registration and Documentation
   • Make sure your boat registration is up to date and on board.
