Mercury Marine this week celebrates the casting of its 2,500,000th stainless-steel propeller in Fond du Lac, Wis.
Simultaneously, Mercury is celebrating its investment cast facility's 40th year of producing boat propellers. The facility opened in 1974.
Mercury said its propellers are recognized globally for best-in-class speed, acceleration and fuel economy. The most recent propeller, Enertia ECO prop, delivers 10 percent improved fuel economy at cruising speed.
"This is a remarkable and important milestone in Mercury's history," Mercury Marine president John Pfeifer said in a statement. "We lead the propeller industry because we have the best people, the best designs and the best materials. We're very proud of the products that come from Mercury's investment cast facility."
Mercury's props are designed by a team of engineers with more than 160 years of combined propeller design experience.
"Using the correct and best-designed propeller to deliver ultimate performance is one of the most important factors a boater can consider, yet it's also one of the least expensive actions they need to take," Mercury Propellers category director Dirk Bjornstad said.
"Every boat application requires a specific type and size of prop if it's going to perform at its highest level. At Mercury we strive to help every boater get the most from their engine and boat. Time on the water is valuable and our props provide the best possible on-water experience."
Mercury's stainless-steel propellers are designed for outboard engines ranging from 9.9 to 300 hp and all sterndrive engines.
