This Solas aluminum propeller for outboards is a 3-blade Amita 3 model with a 9.9″ diameter, 12″ pitch, and right-hand rotation. The propeller has 10 splines and is intended for compatible 20–30 hp outboard motors with a 3″ gearcase and through-hub exhaust.
The propeller is manufactured in aluminum using Solas' squeeze-cast process and features black coated blades. The Amita 3 series blade geometry is designed with a focus on acceleration and top speed. The selected pitch must always match the boat's load and the engine's recommended RPM range.
The pressed-in rubber hub makes the propeller ready for mounting without a separate replaceable hub kit. The engine's original mounting hardware can be used. Compatible spare parts include thrust washer YBTW, spacer YBSP, washer YBWS, nut YBNT, and 1½″ cotter pin, as well as the complete spare parts kit 17032501. The parts are not documented as included.
