Marine Electrical Repair & Installation

Satellite TV systems, onboard Wi-Fi, radar systems, autopilot, and more! We have experience with virtually every component installation for your boat. At Union Marine, we ensure that your vessel’s smart technology is perfectly installed and compatible with your existing systems and components. Whether you’re preparing for a high seas adventure or a Saturday wake surf session, we’ve got you covered.

Prop Repair

A ding in the prop can not only rob your boat of its top performance.. it'll rob your wallet too. A damaged prop reduces fuel efficiency and can also cause damage to your engine and outdrive.

If you have prop damage schedule an appointment at one of our 3 convenient service centers. We can also come to you with our Mobile Service program and ensure that your vessel is in top shape for your next voyage.

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. This will save on costly bad fuel disposal in the spring if not treated. As part of this service 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.
