 Trustindex verifies that the original source of the review is Google. Great service from David today (09/15/2026)!! Spent time diagnosing my skis computer with me and explaining it in detail so I could understand the process and issue i was having. He was willing to help in anyway possible when most others turned me away due to the ski being older than 10 y/o. Highly reccomend this shop!

 Trustindex verifies that the original source of the review is Google. I had both of my jet skis serviced at Moto Marine, and I couldn’t be happier with the experience. They did a great job diagnosing and fixing both jet skis, and everything was completed in a timely manner. The communication and service were excellent, and it’s clear they know what they’re doing. I highly recommend Moto Marine to anyone looking for reliable, professional jet ski service!

 Trustindex verifies that the original source of the review is Google. Honest and professional.  Get my Flyboard parts from David and he recently went the extra mile helping me purchase a hard to find zapata hoverboard for my Flyboard jetski.  Nice to have someone you can trust which is not always the case in the Flyboard industry.
