Quicksilver 5L41500TP SeaCore Bravo III Sterndrive Outdrive 2.20:1 Gear Ratio

The Quicksilver 5L41500TP SeaCore Bravo III is a genuine OEM MerCruiser sterndrive outdrive featuring a 2.20:1 gear ratio and Mercury's advanced SeaCore corrosion-protection system. Engineered for high-performance inboard/outboard applications, this sterndrive delivers exceptional handling in tight marina conditions and powerful, efficient performance at wide-open throttle.

Dual Counter-Rotating Propellers:

The Bravo III's signature twin counter-rotating propshafts grip the water with two propellers—each up to 16 inches in diameter—mounted in tandem and spinning in opposite directions. This design eliminates wasted energy from propeller wash, cancels prop torque for superior tracking, and delivers enhanced steering control in both forward and reverse.
