Bought a jet ski from him yesterday that he was selling for a customer. Great guy, very knowledgeable. Also a man of his word, as soon as I saw the listing I called and said I could be there in a couple hours with cash, knowing that he was getting tons offers because of how good of a deal it was. 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!

Congratulations hope you have a good season with the ski!!
I have an old 1996 Yamaha WaveBlaster 2 jetski that I've let sit for the past 15 years. While the team at full throttle were not willing to take on the work this past spring, they gave me some excellent pointers which helped me get moving in the right direction, which they absolutely did not have to do and is more than any of the other places I called. Thanks to them I have the machine up and running in great shape. Thanks guys!

Wow that's great to hear and thanks for the feedback !!
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 engine is running tip top. Amazing stuff, I will 100% be back.
Steve is simply the best in the business. I honestly can’t say enough good things about his work.
He is an incredibly reliable mechanic who consistently tackles the most challenging technical issues with ease. Not only is his work rock-solid, but his pricing is also very fair and honest. I have the utmost respect for his expertise and wouldn't trust anyone else with my boat. If you want the job done right, Steve is your guy.

Your a great guy to do business with and appreciate your review !! Thank you
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!
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!
Steve is fantastic. He went out of his way to help me. I learned A LOT and got my issues resolved quickly. I can’t speak highly enough of his honesty and knowledge. I wish every shop owner was like this!! 5 stars and then some!
