As the days grow longer and marinas begin to stir, spring is the perfect time to bring your boat out of hibernation and get it ready for the season ahead. Whether your boat has been ashore over winter or sitting quietly on its mooring, a thorough spring check not only protects your investment but also ensures safe, reliable boating from the very first outing.

For those looking for a quick reminder, our friends at Yamaha have put together a short practical guide to preparing your boat for its first launch of the year.

Start with a deep clean

Before you look at anything mechanical, give the hull and topsides a proper clean. Remove algae, grime and salt build up using a suitable marine detergent. This is also the ideal time to inspect the hull for cracks, blisters, or signs of damage that may have gone unnoticed last season.

Below the waterline, check antifouling paint for wear. If it’s flaking, thin or patchy, a fresh coat will improve performance and fuel efficiency over the summer.

Inspect deck hardware and fittings

Once clean, go methodically around the boat and inspect all fittings and fastenings. Look closely at cleats, rails and grab handles. Anything that moves, creaks or shows corrosion should be tightened, serviced or replaced.

Pay particular attention to any valves ensuring they move freely and hose clamps are secure and rust free. A seized valve discovered at sea is a situation no skipper wants to face.

Check safety equipment thoroughly

Safety gear should never be an afterthought. Start by checking lifejackets for damage, mould, failed or outdated inflation cylinders. Make sure any lifejackets are the correct size for regular crew.

Fire extinguishers should be within date and properly mounted. Check flares for expiry and inspect your first aid kit, topping up any missing or outdated items. Now is also a good time to test your bilge pumps, both automatic and manual, to ensure they activate correctly.

Service your engine before you start it

Your engine deserves careful attention before its first start of the season. Visually inspect belts, hoses and mounts for cracking or looseness.

Changing the engine oil and oil filter is strongly recommended, as oil left sitting over winter can contain moisture and contaminants. Ideally you would have used fogging oil before you stored the engine to help protect it from rust and corrosion.  Replace fuel filters and examine the cooling system for blockages or leaks.

Repowering can be an option for some if your engine is old as it can breathe new life into a trusted boat.

Replace old fuel

Fuel degrades over time, particularly modern petrol with ethanol content. If fuel has been left in the tank over winter, consider draining or diluting it with fresh fuel. Water contamination and bacterial growth can cause poor running and blocked filters, often just when you least need trouble.

Adding a marine fuel treatment can help stabilise new fuel and protect the system throughout the season

Examine the propeller and drivetrain

Before launch, inspect the propeller for dings, cracks or bent blades. Even minor damage can cause vibration, reduced performance and increased fuel consumption.

Check the shaft or stern drive for fishing line or debris and inspect anodes for wear. If they are more than half gone, replace them to ensure continued protection against corrosion.

Test all electrical systems

Electrical faults are one of the most common causes of breakdowns early in the season. Check the condition of your battery, terminals and charging systems. Clean off corrosion and ensure connections are tight.

Test navigation lights, cabin lights, instruments, radios and GPS units. Catching faults while still alongside saves frustration later and reduces the risk of being caught without essential systems underway.

Don’t forget steering and controls

Finally, check steering systems and throttle and gear controls. They should move smoothly without stiffness or excessive play. Hydraulic systems may need bleeding, while cables should be lubricated or replaced if worn.

Remember these top 10 preparation tips for spring

1. Wash and inspect the hull early to spot problems before launch
2. Renew antifouling where needed for better speed and economy
3. Service all valves and fittings
4. Check every lifejacket, flare and fire extinguisher
5. Change engine oil and filters before the first start
6. Replace or refresh old fuel to avoid running issues
7. Fully test batteries, electrics and navigation systems
8. Inspect the propeller, shaft and anodes for damage
9. Test steering, throttle and gear engagement ashore
10. Consider repowering - a modern engine can improve reliability, performance and fuel efficiency, often transforming how the boat feels on the water.
