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.

  Great group of people, made the process of trading the old boat and buying a new one easy. The front office area, their service team, and our sales guy (Jeremy) did a great job answering all our questions and getting things done. Looking forward to next year's boating season.

  I bought a boat in August from Jeremy Onos at Winnisquam. He was so fantastic to work with. Friendly, professional, very knowledgeable, responsive, high integrity kind of guy. I will definitely buy my next boat from him. And the rest of the team and service group at Winnisquam Marine were also a total pleasure to interact with. Great quality boats and great marina. Highly recommend.

  We had a great experience working with Jeremy at Winnisquam Marine buying our first family boat. From the beginning, he was extremely helpful, knowledgeable, and accommodating. Being first-time boat buyers, we definitely had a lot of questions (some probably pretty dumb lol), but Jeremy never made us feel that way. He took the time to explain everything and answer anything we asked. We’re about an hour and a half away, and Jeremy even stayed late on a Friday so we could come up and see the boat. Once we got there, he let us take as much time as we wanted looking everything over and we never once felt rushed or pressured into making a decision. Throughout the entire process Jeremy was honest, helpful, patient, and did whatever he could to make everything easy for us. We eventually decided to purchase the boat and honestly couldn’t have asked for a better experience buying our first one. When the time comes to upgrade or make a change in the future, I have no doubt we’ll be going back to Jeremy. Highly recommend him and Winnisquam Marine!
