Frequently Asked Questions

What is included in a complete mechanical repower?

A complete repower includes removing your existing engine, installing a new or rebuilt engine, and reconnecting and testing every system before your boat goes back in the water. Contact our team with your boat's make, model, and current engine to discuss a repower.

Do you service all engine makes and models, or only Mercruiser?

As an authorized Mercruiser dealer, we specialize in Mercruiser sales and service, and we also provide complete mechanical service to all makes and models.

How often should I schedule preventive maintenance?

Preventive maintenance is typically scheduled at least once a season, though the right interval depends on your engine, hours, and usage. Ask our team to recommend a schedule for your boat.

What does an engine tune up include?

A tune up typically covers spark plugs, filters, belts, and fluids, along with a check of overall engine performance, to restore smooth starting, steady idle, and full power.

Do you service outdrives as well as engines?

Yes. Outdrive service, including seal and bellows inspection and gear lube changes, is part of our complete mechanical service.

How often should I have my cooling system serviced?

Impellers, hoses, and heat exchangers should be inspected at least once a season, since a cooling system failure can lead to overheating on the water. Ask our team about a schedule for your engine.

Why does fuel injector cleaning matter?

Dirty injectors can cause rough idling, reduced fuel economy, and lost power. Cleaning restores smooth combustion and helps protect the rest of the fuel system.

Is mechanical service available at both Atlantic Yacht Haven and Travelers Yacht Haven?

Yes. Mechanical service, tune ups, and repowers are available as part of our full service marine group at both locations.

Can I get propeller reconditioning done as part of a mechanical service visit?

Yes. Propeller reconditioning is available alongside your engine service, and our crew can check shaft alignment at the same time.
