Sport catamaran and high-performance center console buyers who opt for Mercury Racing 300R outboard engine power now have a propeller designed specifically for that propulsion package. The Fond du Lac, Wis., company is offering a surface-piercing, five-blade 300-hp CNC cleaver propeller.

According to a press release issued by Mercury Racing this morning, the prop “features a proprietary blade profile that delivers stronger acceleration and more top‑end speed than the Mercury Racing 400-hp CNC Cleaver prop when run on the Mercury Racing 300R.”
“While mainly aimed at twin‑outboard catamaran applications, this new propeller design will also take single‑engine, pad V‑bottom and tunnel boats to a new level of performance,” said Steve Miller, Mercury Racing director of marketing, sales and service, in the release. “There’s no room for error when driving these high‑performance boats and that’s the approach we take when building propellers.”
Though it was primarily designed for the four-stroke, V-8 300R, the new wheel also performs exceptionally well on Mercury Racing’s “legacy” 300X and 300X six-cylinder direct-injection two-stroke outboards, according to the release.
The propeller was designed to “ make the most of the Sport Master gearcase and elevated engine heights.” As such, it reportedly reduces slip percentages in outboard Sport Master applications—averaging 4.5 percent at wide‑open throttle.
Pitch options range from 26 to 40 inches in one-inch increments, with a choice of 15- or 18-degree rake angle. Diameters range from 14-1/2 to 15-1/2 inches. Like all CNC Cleaver props from Mercury Racing, the 300-hp CNC cleaver is shipped in molded plastic case comes with a one-year warranty.
