 Trustindex verifies that the original source of the review is Google. Great customer service. I had an issue with a supercharger they rebuilt. Sent it back to them to find out it was a lubrication issue that damaged it. They went above and beyond and sent me a brand new unit at no charge.

 Trustindex verifies that the original source of the review is Google. Excellent services! Dave was communicative explaining everything he did. We felt prioritized and well taken care of. This was our first experience with Moto Marine and was made to feel confident that our ski was left in great hands. The pricing was reasonable and we highly recommend this shop. Full gratitude!
Update! My husband overuses his ski to fish in the ocean and Dave saved the ski yet again! Thanks Motomarine!! Thanks Dave!!

 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!
