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

Our racers 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 for the APBA Gold Cup on the Detroit River each summer. 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.

July 23, 2016

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 !
