Expert Pontoon & Boat Service from Technicians Who Know Minnesota Waters

About Our Service Department

At T&M Marine, we’ve spent over 40 years keeping Minnesota boaters on the water — and getting them back out there every spring. Our newly expanded service department in Grand Rapids is staffed by certified technicians equipped with the latest tools and diagnostics to handle anything from a routine tune-up to a full engine overhaul. We service all makes and models of pontoon boats, outboard motors, and trailers, so you don’t have to go anywhere else.

Whether you bought your boat from us or somewhere else, we treat every vessel like it’s our own.

Fall Winterizing Services

Don’t let a Minnesota winter catch your boat or pontoon unprepared. Our comprehensive winterizing service protects your investment from freeze damage and keeps your engine ready to fire up come spring. We recommend scheduling early — our service bays fill up fast as the season winds down.

Our winterization package includes:

  • Fuel stabilizer treatment and circulation through engine
  • Lower unit oil change
  • Battery disconnect and storage prep

Spring Startup Services

When ice-out hits Pokegama and Deer lakes, you want to be ready to launch — not waiting in the service queue. Our spring startup service picks up right where winterization left off, getting your boat inspected, tested and water-ready so opening weekend isn’t a wrench-turning session.

Spring startup includes:

  • Battery hook up
  • Engine run-up and systems check
