About Us


Our Story

Founded in 1984, M&M Marine is the world’s largest used personal watercraft parts store.

Mitchel Miller, a former National Champion PWC racer, began selling PWC parts to his fellow racers and local repair shops and quickly became known as the go-to guy in the industry for high quality, affordable replacement parts.

In 2014 M&M Marine owner Mitchel took notice of another growing powersports market - the UTV/Side-by-Side and Spyder market.
He began working within our existing dealer network to purchase sought after parts for these vehicles.

By 2015 M&M Marine became M&M Powersports & Marine, encompassing both divisions of the business.

Mitchel is personally very committed to helping PWC and UTV owners find hard-to-find parts, so if we don’t have a part in stock, he will seek out needed parts through his extensive parts network system.

Listen to our Customers!

When I became the service manager of East Bay Motorsports a year ago, Mitch took the time to come down, introduce himself, and spend an hour discussing how he could be an asset to our dealership.
He made a lot of promises that I was skeptical about because his shop is so far from us. Since then however, he has always made supporting our dealership a top priority, especially during the crucial summer months when customers are yearning to hit the waves.
With the high volume of watercraft we sell and service, M&M has been instrumental in allowing us to deliver a first-class customer experience. Whether he’s personally driving several hours to pick-up or deliver a ski for body-work repairs, shipping an emergency part next-day delivery, or finding us a discontinued part to finish the job, Mitch takes a lot of pride in contributing to the success of our dealership while taking no credit.
His satisfaction comes from making my job easier and ensuring the customer is 100% satisfied when enjoying their ski. His experience and expertise in this business will continue to benefit our dealership.

International Customer Review

I live in Canada on the Pacific coast and rely on the parts order being correct as I cross the border with them.
Mitch is very knowledgeable and prompt to get me what I need ASAP.
I have had the very best service from M&M Marine and would recommend them to everyone. We have processed many perfect orders.
Sorry to see some not so good reviews but you can never satisfy every one.
Cheers! Kerry S.
