The Boat Doc

The Boat Doc We are certified electronics installers for all brands. Warranty Work: We aim to fix your engine right the first time, whether you purchased it from us or not.

The Boat Doc is proudly an authorized full line dealer and service center for Ranger Boats, Triton Boats, Mercury Outboards, Minn Kota and Garmin Trolling Motors. We feel we have the best training available on new product and also have the latest in diagnosing tools for all Mercury engines. If it’s parts you need we can usually get them the next day! Out-of-Warranty Work: Diagnosing your engine pr

oblem quickly saves you labor costs. Some dealers “throw parts” at engines to try to fix them. We feel this is a hit or miss approach that ends up costing you more money. We figure out the problem and get your approval before changing any parts. Tune ups: Sometimes an engine goes out of adjustment or just doesn’t give you the type of performance it used to. Bring it in and we will have it running like new in no time! We have a test pond for running and testing engines to better diagnose running issues. Why? Because it simulates actual running conditions, unlike a garden hose flushing attachment that other dealers use! Winterization: In Wisconsin your boat may be in storage for over half the year and with today’s 10% ethanol fuel winterization has become more important than ever. We know the latest techniques to keep your engine running at its peak performance. We winterize all Mercury and Mariner outboards as well as MerCruiser sterndrive engines. We are so confident in our winterization process that we guarantee your engine will start in the spring! There is no need for a de-winterization process when you come to The Boat Doc! Shrink Wrap: No longer does your boat have to take up space in your garage over winter. You have the option to shrink wrap it! Shrink wrap is a durable plastic that is heated to form fit your boat and protect it from rain, snow, and UV rays. We will shrink wrap your boat to provide top notch protection from the elements. So put your boat outside and save on inside storage fees! Storage: The Boat Doc has storage available in our outdoor fenced in lot, and a large indoor storage shed. Ask us about our winterization, shrink wrap, and storage discount! Our Guarantee to You

We are extremely confident in our ability to repair all Mercury, Mariner and MerCruiser engines. In fact, IF WE CAN’T FIX YOUR ENGINE YOU WILL NOT PAY A DIME!

Here's a sneak peek at some of the sweet rigs we have on the way from Ranger for 2027! It looks like we should start seeing these show up sometime in October, which means if you see one you like, there's a chance we could have you on the water in your new ride before winter sets in.

These are just a few of the 2027 Rangers we have coming. Stay tuned—we've got plenty more on the way!

Last week was a busy one around here as we sent three more boats home with their new owners!

Congratulations to Jason on his purchase of a 2026 Ranger 620FS Cup powered by a Mercury 250 Pro XS! As you saw from the photos last week, he loaded this thing to the max. Those South Dakota walleyes don’t stand a chance with this battleship on the water!

Congratulations to the Ramke family on their purchase of a 2022 Ranger 1880MS Angler powered by a Mercury 200 Pro XS! They called us hoping to find a pristine pre-owned 1880, and they were in luck. This boat checked all the boxes for their whole family, and we know they’ll be making memories in it for years to come!

Congratulations to Josh on his purchase of a 2019 Triton 206 Allure powered by a Mercury 250 Pro XS. He decided it was time to upsize and jumped on this sweet ride as soon as he could. You can bet the fish-catching legacy of this boat will stay true with Josh at the helm!

We wish you all the best of luck on the water, and we thank you for choosing The Boat Doc!

Jason is headed east from South Dakota in the morning to pick up his new 2026 Ranger 620FS Cup! Here is a sneak peek at the sweet build we had the opportunity to do on it.

He decked this thing out with a Garmin Kraken 75", Garmin GPSMAP 1643 on a custom mount at the dash, a 19" monitor at the bow, and Garmin LiveScope 2 LVS44. Powering the entire setup is a Precision Power 12V 150Ah lithium dual-purpose battery and a set of three Tracker Lithium 12V 100Ah deep-cycle batteries. All rigged and wired clean and correct right here in our in-house rigging shop.

Now all that's left is to load it up, head back to South Dakota, and get this 620FS Cup on the water. We appreciate the opportunity to build this one for Jason and can't wait to see it in action!
