The Rock Aqua Jays water ski team has repowered its primary towboat with triple Mercury Racing 300R four-stroke outboards. Founded in 1961, the Janesville, Wis.-based team has won 20 national water skiing titles since 1975. They also hold the Guinness World Record for the largest human pyramid on water skis.
The new 4.6-liter V8 300Rs replace triple Mercury Racing OptiMax 300XS V6 outboards and the re-powered boat made its debut in June 15-16 at the City of Lakes Invitational competition on Warsaw, Ind.
The motors powered the team to a first place overall and a sweep of the box scores. The national championship will also be held in Warsaw in August.
“As expected, the amount of raw power and torque brought to the water is unbelievable,” Kevin Ostermeier, Rock Aqua Jays vice president said in a statement. “While pulling 14-plus barefooters with the OptiMax 300XS outboards, driver Bob Brockman would bring up the throttles a touch more as they stepped off to compensate for increased drag. With the 300Rs, the boat has ZERO hesitation as we all step off.”
Ostermeier continued, “As for our large pyramids with bigger loads (40-plus skiers) that we’ve pulled so far, we’ve preferred a slower trolling speed than normal to start the entire group, knowing the engines can pull us out from the deep with ease. The 300Rs are always hungry for more.”
