Here's what our happy customers are saying...

Kristine M D


"Kristine M DWe have been using the Shell Lake Marine since they opened. Our first purchase was a used pontoon boat, ski boat, dock and one lift. Ended up purchasing a used lift which we quickly upgraded to another new one. We also upgraded the ski boat to a used sea ray speed boat that we love. Our pontoon is a 1994 which runs like a champ as well as the sea ray. That’s because Tom, Kourtney and Crew take care of ALL our boats, lift and dock needs. They service, winterize, and store our boats. Anytime we have a problem they are there to help us, even on a few holiday weekends which was greatly appreciated, and not forgotten. There is no place we would go other than Shell Lake Marine. Support this Hometown Family run Business. There is NO PLACE that compares. There’s not enough stars in this review to tell you how we really feel about them. Thank you for everything you have done and continue to do for us. Bill & Kris"

"We purchased a small cabin on Shell Lake in 2019 and bought our Pontoon Boat, lifts and dock all from Shell Lake Marine. Tom, Kourtney and the entire staff were outstanding. They are extremely knowledgeable and their products and support are second to none. 5 stars all the way!"
