Home

The Marine Prop Riders club was established in 1951 to promote Inboard Hydroplane Racing in the Detroit area.

Our drivers and owners range in age from their teens to 70-some, and represent at least seven classes of racing from the 1.0 Litre class to the thundering supercharged big-block powered Grand Prix hydros, as well as the Unlimited Hydroplanes that race in the APBA Gold Cup class on the Detroit River. We also have members in the Vintage class who run exhibition laps with the raceboats of years gone by.

We set World Records!

MPR members are involved in presenting a number of races in the region, many are drivers and others participate as crew, scorers, referees, rescue personnel and event volunteers. You're welcome to join us.

CS Mott Lake - Drone video early Saturday AM
August 23, 2023

The CS Mott Lake area is gorgeous! It's perfect for hydroplane racing for many reasons including the lake itself, the fantastic Bluebell Beach viewing area, and a nice pit area. Thanks to Erat Racing for the drone video. I think I see a Drivers Meeting at the pit entrance.

This race was something to see... Andrew Tate way out in front but breaks down just short of the finish line, UGH! After that what could be better than Mario Maraldo (owner) and Bobby King (driver) taking the win in Baby Doll III !
