I want to start by saying that Jayce is extremely professional and knowledgeable about everything that has to do with boats and marine engines. I’ve used keys Marine Services a few times for services and repairs and I’ve always felt that I was using the best people for the job, I will not hire anyone else to work on my boat and the peace of mind that you get knowing they are top notch specially when it comes to boating is priceless. I honestly can’t recommend this company enough, FIVE stars all around 👍.

I only write a few reviews a year but this one was absolutely earned. This was my first time using Keys Marine Service for the annual maintenance on my Yamaha 200’s…This was a great experience! I reached out to Jayce about 10 days ago and was promptly (within an hour!) replied to and provided with a solid quote for the service. I scheduled the service but due to scheduling conflict at my marina had to re-schedule and Jayce was very accommodating and professional about the issue. On service day he showed up on time, did a thorough checkup of my engines, did the required service, provided pictures of the service and materials used…Wow what a great pleasure to finally find a mechanic in the middle Keys that you could tell takes pride in his work. The price of the service was very competitive and the service provided was outstanding. If you’re looking for a reliable, professional and competent marine mechanic in the middle Keys this is your company. Thanks again to Jayce and Keys Marine Service!

Jayce helped us get out on the water when we were having engine trouble with our boat. He was professional and knowledgeable. He diagnosed and repaired our issue. He made sure everything was how it needed to be before we got out on the water. We’ve already decided that we will need to get back to Key Largo from North Carolina just so Jayce can do the yearly service in our boat. Yes, his service was that good!
