Vessel Winterization

Proper preparation & winterization of your vessel is critical to ensuring that your engine and its critical components survive the freezing winter temperatures unscathed.

As part of this service, we’ll add fuel stabilizer to your fuel to preserve it during the winter months —which can save on costly bad fuel disposal in the spring, if not treated. Then we’ll run your boat on our brine mix of oil and fuel to ensure all the internal fuel regulating components are coated with a thin layer of oil to keep the from getting gummed up while in storage.

Marine Electrical Repair & Installation

From Satellite TV systems, to On-Board Wifi, Radar Systems, Auto-Pilot, and more, we’ve seen just about every component possible to install on a boat.

We’d be happy to ensure that however “Smart” you choose to make your vessel, that everything is installed perfectly and works with your existing systems and components before heading out on the high seas, or the Saturday wake surf session.

Fiberglass & Gel Coat Repair

Hit the dock and need a little fiberglass repair? It happens to every boater at some point. Have no fear though, we’ve seen and fixed it all and our expert team will have your boat fiberglass and gelcoat looking like nothing ever happened.

Prop Repair

A ding in the prop can not only rob your boat of its top performance, it’ll rob your wallet by reducing fuel efficiency, or even causing damage to your engine and outdrive.
