Overview

Altitude propellers set the standard for high-performance outboard-powered boats using thru-hub exhaust. They are designed to provide ultimate top-end speed without sacrificing low-speed maneuverability or planing performance. Fully CNC-machined using proprietary 5-axis technology, Altitude propellers feature broached splines for either 1.25” (300-400hp) or 1.50” (500hp) prop shafts. Their marine industry-first modular barrel design allows for dialing in stern lift and supports additional customization options. 

Four different barrel lengths are available for custom order in 0”, 1”, 2” and 3” options. Available in 18-degree rake from 26” to 28” pitch, and 15-degree rake from 30” to 35” pitch. 

All Altitude propellers ship in a Mercury Racing Propeller Case.
