THE X FACTOR
The new SpitFire® X7 is the first propeller for 75-115hp outboard-powered boats manufactured with Mercury Marine proprietary X7 Alloy. X7 Alloy is 30 percent stronger and four times more durable than conventional steel, allowing Mercury Marine to design propellers unimaginable to other manufacturers.
The impossible just became reality as the new SpitFire X7 will propel your 75-115 hp outboard powered boat to levels that have never existed. The small diameter generates unmatched acceleration while aggressive cup and rake produce exceptional top speeds to maximize your boat’s performance.
