This aluminum propeller for Yamaha and Selva outboard motors is a Solas Amita 3 model with three blades, a 9.9" diameter, and a 10" pitch. The propeller features right-hand rotation and a 10-spline connection to the propeller shaft.
The Amita 3 series is manufactured in aluminum using squeeze casting, which provides a dense casting structure and stronger blades than traditional die-casting. The blade geometry is developed with a focus on acceleration and top speed. The high-gloss black finish protects the surface, and the aluminum propellers are constructed with four layers of anti-corrosive paint and tested in salt spray for more than 500 hours.
The propeller has a fixed, factory-installed, pressed-in rubber hub. Therefore, a separate interchangeable hub kit is not required. Exhaust is routed through the hub, and the design is intended for 3" gearcases with a 10-spline propeller shaft. Original mounting hardware can be reused if the parts are in correct and sound condition.
Compatible engine models
Compatibility includes Yamaha 20 hp from 1996-1997, Yamaha 25 hp from 1980 onwards, Yamaha F20 4-stroke from 2018 onwards, Yamaha F25 4-stroke from 1998-2006 and from 2010 onwards, and Yamaha 30 hp from 1979-2002. It also fits Selva 25 hp 4-stroke Moray and King Fish.
Compatible Yamaha-built Mariner engines include Mariner 25 hp from 1980-1984, 28 hp from 1976-1979, and 30 hp from 1979-1990. Additional compatibility includes Parsun F20, F25, T20, T25, and T30 in the 20-30 hp class, provided the engine has a 3" gearcase, 10 splines, and through-hub exhaust.
Engine power alone is not sufficient for choosing a propeller. Check the gearcase, spline count, rotation direction, engine year, and the permitted RPM range. The correct pitch also depends on the boat type and load.
Replaces OEM numbers
The propeller cross-references to Yamaha OEM 664-45945-00-EL. Related Yamaha numbers are 664-45945-00-36 and the newer replacement number 664-45945-00-00. Other documented cross-references are Michigan Wheel 022002, EMP P3211-0988-10, Polastorm 2121-3099-10, and Mercury/Mariner 81649M. The manufacturer part number for this Amita 3 propeller is 3211-099-10.
Related mounting parts
Documented mounting parts for the B-hub are YBTW thrust washer, YBSP spacer, YBWS washer, YBNT propeller nut, and a 1 1/2" cotter pin. The parts are found together in hardware kit 17032501 and are not documented as included with the propeller. Rubex 3 9211-099-10 with RBX-B30 is an alternative with an interchangeable hub system and is not the same construction as this propeller.
