Mercury Marine has introduced SpitFire X7, a stainless steel propeller designed for the 75-115hp outboard class.
According to Mercury, the SpitFire X7 is the first in the 75-115hp engine class to be marketed with Mercury’s proprietary X7 alloy, which is 30 percent stronger and fourtimes more durable than conventional steel. Using the X7 alloy and building off the best-in-class aluminum SpitFire, the SpitFire X7 will significantly improve acceleration, top speed and holding compared to other stainless steel propellers in its class.
“A high-performance propeller is the most cost-efficient way to improve a boater’s experience, and for the 75115hp outboard class, the SpitFire X7 delivers,” said Jared Reichenberger, brand manager for Mercury Propellers. “With gains of up to 1.5 miles per hour and 0-20 acceleration improvements by five-plus seconds versus other stainless propellers, the SpitFire X7 will be a staple in the Mercury propeller line-up for many years to come.”
