This Solas Amita 3 aluminum propeller for Tohatsu is a 3-blade, right-hand rotation propeller with a diameter of 8.5″ and a pitch of 9″. This variant has manufacturer number 5011-085-09 and is intended for a 12-spline propeller shaft.
The propeller is made of aluminum and features a fixed, pressed-in rubber hub. Exhaust is discharged through the hub, and the design is intended for engines with a 2½″ gearcase. The nominal pitch of 9″ corresponds to approximately 229 mm of forward travel per revolution without slip.
The Amita 3 series is manufactured using pressure casting, which provides a virtually non-porous aluminum material and strong propeller blades. The aluminum propeller has a corrosion-resistant coating system with four layers of paint, which has been tested for more than 500 hours of salt spray.
Compatibility
The variant-specific engine designation is Tohatsu 9.8 hp, specified as 10R 4S from 2011, with a 12-spline propeller shaft. Manufacturer number 5011-085-09 is also documented for Mercury 8 and 9.9 hp 4-stroke non-Bigfoot with a 2½″ gearcase, 12 splines, and through-hub exhaust.
The fixed rubber hub is factory-installed, so a separate hub kit is not required for the propeller itself. Engine-specific washers, nut, cotter pin, and other mounting hardware must match the specific engine and propeller shaft.
The pitch of the propeller affects engine RPM, acceleration, and speed. The correct propeller choice therefore also depends on the boat's hull, load, and the engine's achieved RPM at full throttle.
Always check the engine model, gearcase, number of splines, and original part number before purchase.
