“I was referred to SMS by a reputable company and my experience with them has been outstanding. It's not an easy task finding a qualified marine mechanic that actually cares about the job at hand and won't settle until the customer is completely satisfied. Highly recommended”

“My boat needed a major clean up and Richard and the team did everything I expected and more. The quote was much better than others and they did a great job. Would definitely recommend them. Thank you.


“Highly recommended for a quick and reliable service! Hamish tried to troubleshoot our engine troubles via facetime and figured out that there was an internal problem. He made time for us to swing by and diagnose the problem. The next day we were able to pick the boat up and had happy days on the water! Thanks again so much SMS!”

“Highly recommended! After years of having boat mechanics trying to sting me for every single dollar they can and making up problems that don't exist i was not expecting the level of service and quality of work these guys did. Along with Gladesville bridge marina I couldn't be happier with the service and price.”
