Mercury Racing announced the all-new 300hp Five‑Blade CNC Cleaver propellers this month. These props are designed specifically to maximize performance of 300 horsepower outboards Featuring a proprietary "surface‑piercing" blade profile Mercury promises these new propellers will deliver stronger acceleration and higher top‑end speed than the Mercury Racing 400hp CNC Cleaver prop when run on either the older legacy Mercury Racing 300XS and 300X outboard models or on the new Mercury Racing 300R outboards.

“While mainly aimed at twin‑outboard catamaran applications, this new propeller design will also take single‑engine, padded‑vee‑bottom and tunnel boats to a new level of performance,” said Steve Miller, Mercury Racing director of marketing, sales and service. “There’s no room for error when driving these high‑performance boats and that’s the approach we take when building propellers.”

The CNC Cleaver propellers are custom made-to-order and available with thousands of pitch, rake and diameter combinations to match nearly any vessel. These props are machined exactly to ensure proper and consistent handling, speed and lift. Designed to leverage the Sport Master gearcase and elevated engine heights, this 300hp Five‑Blade Cleaver prop promises to dramatically reduce slip percentages in outboard Sport Master applications, averaging 4.5 percent at wide‑open throttle (WOT).

(The pitch range is 26 to 40 inches in one‑inch increments. The diameter range is 14.5 to 15.5 inches and there is a choice of 15‑degree or 18‑degree rake.

As always, this Mercury Racing propeller will carry a one‑year warranty to cover the propeller in its entirety (including any damage done to other parts if a failure of the prop does occur).
