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.

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 charge, load test and reconnect
- Engine run-up and systems check
- Fluid level inspection (engine oil, lower unit and hydraulic steering)
- Flagging any needed repairs with a written quote
