Mercury Marine introduces SpitFire X7 propeller

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

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 four times 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 75-115hp 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 lineup for many years to come.”

The SpitFire X7 is available at Mercury dealers.
