Testimonials & Reviews
What People are Saying
 

We have been taking our boats to Cole's for about 15 years after some very poor experiences at other well knows shops. Not only did he really fix our motor but he also gave us lessons in how to take care of it properly
— Jodie Shulsen
What I loved about this place was Gary totally took his time to educate me on what and why he did the repairs he did. Left there with a solid motor, piece of mind, and an education. Even did a couple minor extras free last minute because he "just can't let that leave like that". Just that kind of place, not many like it left. This is now my boat shop
— Joshua Murphy

I Went in to get some rebuild kits for my carburetors and the mechanic there knew about the boat I had recently purchased told me the seller was full of it and gave me the actual run down of what was wrong with my outboard since he was the last one to work on it and with that help and a service manual he sold me I was able to get my boat running the next day. They definitely have my business in the future.
