Captain Steve B

In my 30+ years of boating, I have not found a mechanic I trust more than Ross for his knowledge, integrity, and willingness to help in any way he could.

Steve G

I have had over ten different marine mechanics with Volvo Penta certifications perform both preventative and corrective maintenance on our Volvo Penta D6 310 D/B engines with IPS-A drives and Ross is one of two that I still trust and use and he is without question the most competent and reliable.

Brad T.

He arrived at the marina on time, had the proper tools and test equipment and service parts on hand, to conduct the service. His attention to detail was exceptional, down to protecting the decks and other areas of the boat. He was very efficient in completing his work.
