We are your local Mercury, Mercruiser and PCM dealer with PCM and Mercury trained and certified technicians available to help Monday through Saturday. We provide service for all parts of your boat, from the engine, to the hull, canvas, or even transportation. When it comes to your boat, we're here to help you with whatever you may need. Our goal is to maximize your time on the water and work to improve your boating experience!

Facility Tour

We are excited to show our customers exactly where their boats go when they come in for service or storage. Our new service shop was built in 2012 and our technicians love the space. Along with new buildings, we have also increased our dock space at our Lake of Bays location to allow our customers some room to dock while spending time in Dorset. Stop in and ask for a tour!
