Winter has come and gone, and it’s time to start waking your boat up for the season. Spring maintenance is more than just a deep clean—it’s about ensuring your boat is safe, seaworthy, and ready for action.

Here’s your 2025 spring refresh guide. 

Pre-Check (Paperwork & Compliance)

Before you even step aboard, check that all necessary documentation is current and accessible. This includes:

• State Registration & Federal Documentation – Make sure your boat’s registration is up to date and displayed correctly.
• Proof of Insurance – Review your boat insurance for any necessary updates or renewals.
• Boater Safety Certificate – If required in your state, make sure you and any frequent operators have valid safety certification.
• Navigation & Safety Compliance – For boats over 39.4 feet, a copy of the Inland Navigation Rules is required onboard.

Safety Equipment Check

Your boat should always be stocked with safety gear that is functional and up to Coast Guard standards. Here’s a quick rundown:

• Life Jackets – Every passenger should have a properly fitted, Coast Guard-approved PFD.
• Fire Extinguishers – Check that you have the correct number of extinguishers based on boat size. 
• Flares & Visual Distress Signals – Inspect expiration dates and replace as needed.
• Sound Signaling Devices – Horns, whistles, or bells must be in working order.
• Navigation & Anchor Lights – Make sure all required lighting works properly for safe nighttime operation.
• First Aid Kit & Emergency Gear – Stock up on medical supplies, spare batteries, and emergency tools.

Systems Check: Power, Fuel, & Engine Maintenance

Nothing kills the mood of your first spring ride like a dead battery or engine trouble. Take the time to go through these steps:

Electrical System

• Charge and reinstall batteries; clean and tighten all connections.
• Check onboard electronics, including GPS, radios, and lights.
• Inspect wiring for corrosion or wear.

Fuel System

• Replace fuel filters and inspect fuel lines for cracks or leaks.
• Fill the tank with fresh fuel if it sat stagnant during winter.
• Look for signs of water contamination in the fuel system.

Engine & Cooling System

• Change the oil and replace oil filters.
• Inspect belts, hoses, and clamps for wear.
• Test and replace coolant if needed.
• Run the engine at the dock to check for smooth operation.

Hull & Propulsion Check

After months of storage, your hull and propulsion system may need some TLC:

• Hull Cleaning & Waxing – Remove grime and apply a protective wax coat.
• Check for Cracks or Blistering – Small cracks can lead to bigger problems if ignored.
• Inspect Propellers & Shafts – Look for dings, bends, or damage.
• Replace Anodes – These prevent corrosion of metal parts underwater.
• Test Steering & Throttle Controls – Ensure they operate smoothly with no sticking or stiffness.

Plumbing, Ventilation & Interior Refresh

• Flush the fresh water system and check for leaks.
• Inspect marine sanitation devices for clogs or needed repairs.
• Ensure ventilation systems are free of blockages and functioning properly.
• Deep clean upholstery, carpets, and storage areas.

Trailer Tune-Up (If You Use One)

If your boat spends the off-season on a trailer, don’t forget to check:

• Tires & Bearings – Inflate tires to the correct pressure and grease bearings.
• Brakes & Lights – Test trailer lights and brakes.
• Bow Straps – Inspect for fraying and replace if necessary.
