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

I have known and dealt with Dean for approx. 25 years and he is the ONLY mechanic that touches our machines, period. We ride as a group of families mostly and the last thing I need are breakdowns in the woods with women and small children. I followed him from downstate where he lived and worked before to Northern MI where his current shop is located. BTW, his shop/facilities are second to none. He knows his business, is professional, efficient, knowledgeable and his pricing is more than reasonable. My adult son, my siblings and many many friends have chosen to work exclusively with Dean over the years since I first introduced them due to his exceptional knowledge, expertise, cost and ethics. If it doesn't need fixed now, he will tell you but will make recommendations. Every dollar I have spent there has been well worth the $$$. When we have looked for used machines/equipment for sale in the past, I always call Dean to see what he has or knows about, especially the machines he has maintained. Obviously I can't say enough positive things about Dean and Precision Motor Sports & Marine..... 10 Stars ********** Brook Smith and Family Fenton, MI Brook Smith
