O-ring sealed cylinder heads replace the traditional head-gasket heads, providing greater head stability, less cylinder distortion and improved engine cooling.
Carbon fiber, single-stage reeds have two to three times the life of dual-stage fiberglass reeds and produce comparable power.
Seven-petal intake system, fed by six individual fuel injectors, ensures quick starting and optimal engine performance throughout the 7500 rpm operating range.
Solid engine mounts improve engine response and overall boat performance at higher speeds.
The Sport Master gearcase features a new heavy-duty propshaft for enhanced durability.
