The Ultimate Pre-Summer Boat Maintenance Checklist

As the warm weather rolls in and boating season begins, now is the perfect time to make sure your vessel is ready to hit the water. At Johnson Bros Marine Services, we’ve put together the Ultimate Pre-Summer Boat Maintenance Checklist to help Sydney boaters prepare their boats for a safe, smooth, and enjoyable season on the water. Whether you're cruising around Pittwater, launching at Bayview, or fishing off the Northern Beaches coast, this guide will help ensure your boat performs at its best.

 

1. Engine Inspection & Servicing

Your engine is the heart of your boat, don’t skip this step. Check the following:

  • Oil and filter change
  • Spark plug inspection/replacement
  • Cooling system flush
  • Fuel system check (lines, tank, filters)
  • Battery charge and connection check
  • Propeller inspection for damage or wear.

Pro tip: Book a professional marine service early in the season to avoid the rush. At Johnson Bros Marine Services, we offer marine engine servicing across the Northern Beaches.

 

2. Electrical System Check

Salt, moisture, and long periods of inactivity can take a toll on your boat’s electrical systems. A full electrical check ensures your boat stays safe and compliant on the water. Check the following:

  • Battery condition and voltage
  • Navigation and anchor lights
  • Bilge pump functionality
  • Horn, gauges, and switches
  • Fuses and wiring connections.

 

3. Hull & Propulsion System Inspection

Inspect your boat’s hull and underwater gear for signs of damage or marine growth. Check the following:

  • Inspect hull for cracks, blisters, or chips
  • Clean and inspect the propeller
  • Inspect shaft seals and rudder (if applicable)
  • Check transom for wear or damage
  • Inspect trailer rollers and guides (if trailered).

Pro tip: If you store your boat in water year-round, consider applying fresh antifouling paint before summer.

 

4. Safety Gear & Equipment Check

Ensure all required safety gear is in good working order and meets NSW regulations. Don’t risk fines or safety issues, inspect everything thoroughly before your first summer outing. Check the following:

  • Life jackets (correct sizes and accessible)
  • Flares (check expiry dates)
  • Fire extinguisher
  • First aid kit
  • Emergency radio / EPIRB
  • Anchor and line.
     

5. Clean & Detail Your Boat

A clean boat not only looks great but helps identify small issues early. Start the season fresh with:

  • Full exterior wash and polish
  • Interior clean (seats, compartments, floors)
  • Windscreen and canopy cleaning
  • Upholstery and canvas inspection
  • Mould and mildew treatment.

Bonus: A detailed boat improves fuel efficiency and resale value.

 

6. Update Your Registration & Documents

Make sure all your boating paperwork is up to date and keep physical or digital copies on board just in case. These include:

  • Boat registration
  • Marine licence
  • Insurance details
  • Service history/logbook.
