Marine Engine Maintenance: A Must-Know for Safe Yacht Passage Making

Keep Your Yacht Engine Running Smoothly with Wright Marine

Whether you're embarking on a long-distance yacht delivery or receiving bespoke yacht handling

tuition, one thing remains critical—your marine engine's reliability. At Wright Marine, we don’t just deliver yachts; we prepare skippers and owners to operate their vessels confidently, starting with one of the most vital components: the engine.

In this blog, we’ll guide you through essential marine engine maintenance practices to keep your yacht performing at its best—whether you're under tuition, in open water, or preparing for seasonal use.

Why Marine Engine Maintenance is Critical for Yacht Owners

Marine engines endure intense conditions: salt, moisture, vibration, and long operating hours. Skipping regular maintenance risks:

• Unexpected breakdowns during delivery or training

• Delays to cruising plans

• Increased repair costs

• Shortened engine lifespan

• Decreased safety and performance

  
  

As part of our bespoke tuition programs at Wright Marine, we emphasize hands-on engine checks and maintenance awareness. Knowing how to spot and prevent problems is a crucial skill for every yacht owner and skipper.

5 Essential Marine Engine Maintenance Tips

1. Regular Oil Changes

Change the oil and filter every 100 engine hours or once per season—whichever comes first. Marine engines operate under heavy loads, so fresh oil is vital for cooling and protection.

➡️ Use marine-grade oil and filters approved by your engine manufacturer.

2. Inspect the Cooling System

Salt and scale buildup can cause overheating. Regularly flush the cooling system with fresh water—especially after every saltwater trip. Check the water pump and coolant levels regularly.

➡️ Overheating is one of the top causes of engine failure during passage making and is one of the easiest to avoid with regular checks of strainers.

3. Fuel System Maintenance

Change fuel filters regularly and keep an eye on fuel quality. Water or contaminants in the fuel can damage injectors and stall the engine mid-voyage.

➡️ We can provide basic engine maintenance to show how issues can be avoided.

4. Check and Replace Belts & Hoses

Look for cracks, fraying, or slack in belts. Hoses should be supple and leak-free. Replace any worn components to avoid breakdowns at sea.

➡️ A snapped alternator belt mid passage could leave you without power or charge.

5. Battery Maintenance

Inspect terminals for corrosion, check voltage, and ensure batteries are securely mounted. Marine batteries degrade faster due to constant vibrations and moisture exposure.

➡️ Check how quickly are your batteries discharging? are the cells correctly topped up ?

Visual Inspections Before Every Trip

A quick pre-departure check can catch problems early. Look for:

• Leaks

• Unusual smells

• Loose wiring

• Disconnected hoses

➡️ Our yacht delivery skippers never leave the dock without this step and neither should you.
