If there's one question we hear all the time, it's this:

"How often should I service my boat?"

The short answer? At least once a year or every 100 engine hours- whichever comes first.

Waiting until something breaks usually means a bigger repair, more downtime, and more money. Routine maintenance is about catching small problems before they turn into expensive ones.

Your Boat Works Hard

Florida isn't easy on boats.

Saltwater, heat, humidity, long runs, and sitting at the dock all take a toll on your engine and onboard systems. Even boats that don't get used often still need regular inspections.

Just because it starts doesn't always mean everything is working like it should.

What Should Be Checked?

Every boat is different, but routine service often includes:

  • Engine inspection

  • Oil and filter service (where applicable)

  • Fuel system inspection

  • Lower unit or gearcase service

  • Battery and charging system check

  • Cooling system inspection

  • Belts, hoses, and steering components

  • Electrical system inspection

  • Propeller inspection

  • Diagnostic scan when applicable

Staying ahead of maintenance helps keep your boat reliable and ready when you are.

Signs It's Time to Call

Don't ignore these warning signs:

  • Hard starting

  • Loss of power

  • Engine running hotter than normal

  • Rough idle

  • Warning alarms

  • Electrical issues

  • Fuel smell

  • Excessive vibration

  • Unusual noises

Small problems rarely fix themselves.

Preventative Maintenance Saves Money

We see it all the time.

A worn impeller becomes an overheated engine.

A neglected fuel filter becomes a no-start situation.

A loose electrical connection leaves you stranded.

Routine maintenance is almost always less expensive than repairing the damage after something fails.

Why We Focus on Diagnostics

At Costa Marine Group, we don't believe in guessing.

Our approach starts with understanding what's actually happening before recommending repairs. Accurate diagnostics help avoid unnecessary parts replacement and get your boat fixed the right way.

Whether it's scheduled maintenance or tracking down an issue that's been driving you crazy, we take the time to do it right.

Keep Your Boat Ready

The best day to service your boat isn't after something breaks—it's before it does.

Regular maintenance helps protect your investment, keeps your boat performing the way it should, and gives you more time on the water.
