What We Work On

Each service is delivered by experienced technicians who know boats inside and out.

Mechanical Services

Engine repairs, tune ups, lower unit work, impeller replacements, and full rebuilds. Outboards, stern drives, and inboards.

Engine Diagnostics

Computer diagnostics for Mercury, Mercruiser, Yamaha, and other marine engines. We find the problem before we start turning wrenches.

Electrical Services

Wiring, battery systems, gauges, lighting, and onboard electronics. If it runs on power, we can troubleshoot it.

Fiberglass Repair

Gelcoat damage, hull cracks, structural fiberglass work, and cosmetic repairs. We handle it all in house.

Routine Maintenance

Oil changes, filter replacements, fluid checks, belt inspections, and seasonal tune ups to keep your boat running right.

Winterization

We prep your engine and systems for the off season so nothing freezes, cracks, or corrodes over winter. Includes fogging, fluid drainage, fuel stabilization, and full system check.

Spring Commissioning

When the season starts, we get your boat back in the water. Battery install, fluid top off, systems check, and a once over to make sure everything is ready.

Warranty Repairs

Authorized warranty service for Bennington, Bayliner, Monterey, Mercury, and Mercruiser. We file the paperwork and handle the repair.
