I met Dean over 20 years ago when I wanted to have a porting job on one of my SkiDoo’s . I was impressed with the quality of workmanship he did. The sled ran great and was extremely durable. At that time his shop was in Fowlerville and we lived in Novi. When he moved to northern Mi I continued have him do all of the work on my boats, sleds and bikes and the works was always top notch. Dean is a master with all aspects of snowmobiles, dirt bikes and marine applications. Dean was instrumental in putting together a “sleeper” high performance sled for me working on everything from the engine to the suspension. That sled was amazing on both the trail and the lake; we even went on an 1800 mile trip through Canada without incident. Dean also rebuilt my YZ250 engine & suspension and 2 tired SeaDoo engines for me which are now all running like new. Dean’s shop is fully equipped to perform machining, boring, welding, part preparation and just about everything needed to work on all motorsport equipment. That’s reassuring to me knowing the same level of detail is in all aspects of his work. I wouldn’t go anywhere else to have my work done on sleds, bikes, boats or anything else motorsports related. He’s the best! Bob & Sandy, Houghton Lake, Mi Bob Betrus

We had an Intermittent Starting problem with my Daughter's Ski Doo Snowmobile. It only took 3 days to assess the problem. There was a poor connection at the fuse box and terminal blades were tightened to insure a solid connection would be maintained. The snowmobile was left for 2 additional days and randomly started to insure the engine cranked and fired every time. Dean, the Owner and his Lead Technician updated me and were outstanding with their communications. When presented with the Invoice for Labor I believed there was a mistake and was not charged enough for their diagnosis, repair and testing after the repair for all of their Labor. Dean told me that covered their labor. I was expecting to be charged 3 times greater than the final Invoice! That is Integrity that you do not find consistently with Businesses today! Between my Daughter and my family we have 7 older snowmobiles. Precision Motor Sports and Marine have my business for a lifetime. I was blown away by their Technical expertise, Customer Service and Integrity! Thanks so much and Well Done! Joe Navarre
