"I highly recommend Stefan and the crew at First Coast Marine. He and his team have kept my older boats on the water through expert trouble shooting and efficient repairs. Affordable and prompt. I've used several local marine repair shops, including boat and engine OEMs, and First Coast is by far the best."

"Stephan and Zanver troubleshoot the problem right away and had my motor running within 15 minutes. Ordered the parts needed and all fixed within 2 days. Very efficient and straightforward. Thank you!"

"My technician was very thorough despite my Boat design not making it easy to do the job. He was very good about communicating and keeping me informed about what was happening. Every customer is a priority at First Coast Marine."

"I called 1st Coast Marine yesterday morning and they said bring it in right away. I dropped my boat off around 10:30 and within 1 hour he called me back and told me what needed to be fixed. I went and picked up the parts and by 3pm my boat was ready to roll. As a new boat owner, he even gave me a lesson on how to set my motor right in the water. I will never go to any other marine mechanic — this place gets a 5 star from me. Family owned and very mechanically inclined."

"I called Stephan about a lower unit lube change and he did it that day for well under competition prices. Also had him replace my water pump on the outboard too. Reasonable prices, easy to get in to. Go see him. He will treat you right."
