Bought a jet ski from him yesterday that he was selling for a customer. Great guy, very knowledgeable.

I couldn't get my boat into my normal dealership for a month with engine trouble. I called Steve and he was willing to take a quick look and maybe get me fishing again. He 100% didn't have to do this because everyone is swamped this time of the year. In less than 24hrs of calling Steve I was back on the water and…

First time customer and was extremely happy with Steve’s quality of work and professional communication. He installed a new battery along with new electronics and everything works perfectly. The spring tune up has my 30 year old 2-stroke running better than ever. Easy five stars!

I asked for his word that he wouldn’t sell it on me and sure enough he didn’t. Even though getting numerous offers above asking price, he kept his word and held it for me. Transaction went smoothly, I would highly recommend doing business with him!

Update 2 years later ..... Every interaction with Full Throttle Marine has been fantastic! In addition to the comments from my earlier review I was totally impressed with a recent appointment for winter prep. Steve took care of the standard work, explained everything that was completed but totally impress that he found two items that needed attention, one would have been a major issue next time out with the boat. He the parts on hand to fix the problems and completed the repairs. Great attention to detail, had the parts on hand and I'm appreciative of the level of service provided. Hats off to Steve and team. Cost is more than fair and appreciate that as well. Review from a few years back ... First time using Full Throttle Marine and was very happy with them. Quick and easy to book an appointment, good communication, super knowledgeable folks, happy with the work they did and at a very fair price.

Steve was awesome! He took the time to show us a few things (we’re new to boating) and explain everything without even charging us for his time. Super helpful, professional, and just a really good guy. We will definitely be using his services!
