Mercury Marine debuts new propeller for outboards

Mercury Marine introduced SpitFire X7, a stainless-steel propeller.

Mercury Marine introduced SpitFire X7, a stainless-steel propeller designed to improve all performance facets of the growing 75- to 115-hp outboard class.

The SpitFire X7 is the first in the 75- to 115-hp engine class to be marketed with Mercury’s proprietary X7 alloy, which the company says is 30 percent stronger and four times more durable than conventional steel.

That will improve acceleration, top speed and holding, the company says.

“A high-performance propeller is the most cost-efficient way to improve a boater’s experience, and for the 75-115-hp outboard class, the SpitFire X7 delivers,” Mercury Propellers brand manager Jared Reichenberger said in a statement. “With gains of up to 1.5 miles per hour and substantial acceleration improvements versus other stainless propellers, the SpitFire X7 will be a staple in the Mercury propeller lineup for many years to come.”
