Annual and 100-hour service

Annual and 100-hour boat service in Florida

Every 100 hours or once a year, whichever comes first. Factory-trained technicians at all four stores, on Yamaha and Mercury outboards, wherever you bought the boat.

When to book

100 hours or one year.

Whichever comes first. Florida boats run year-round, so most owners hit the one-year mark first.

Before a lay-up or hurricane season.

Oil, fuel and rubber parts age even when the boat sits.

Anything feels off.

Hard starts, alarms, rough running or a new noise: don’t wait for the annual.

What each service includes

Each service includes everything in the one before it, plus more. Exact intervals vary by engine; we follow the Yamaha or Mercury schedule for yours.

One visit, the whole boat.

Rigging, electrical, canvas and repairs under the same roof.

Annual service questions

Is a 100-hour service the same as an annual service?

Yes. It’s one service, due at 100 hours or one year, whichever comes first.

Do you service boats I didn’t buy from you?

Yes. We service Yamaha and Mercury outboards on any boat. For other engine makes, call your store.

My boat has twin or triple outboards. Are they done together?

Yes, in one visit, each engine to its own hours.

What does it cost?

It depends on the engine, how many you have and what’s due. We quote it for your boat before any work starts.
