This Solas outboard propeller is an Amita 3 aluminum propeller with a diameter of 8.5″ and a pitch of 9″. It is designed for select Johnson and Evinrude outboard motors with a pin-drive propeller shaft.
The propeller has three blades, standard right-hand rotation, and a fixed, integrated pressed-in hub. Power is transferred via a drive/shear pin instead of a standard splined hub connection. The design is intended for motors with pin-drive and non-thru-hub exhaust.
The 8.5″ diameter corresponds to 215.9 mm. The 9″ pitch corresponds to a theoretical advance of 228.6 mm per revolution, without accounting for slip. The manufacturer part number is 2011-085-09P, which also appears in the short form 2011-085-09. The internal hub reference is 6S-RB, P/N 170201.
Compatible engine models
Compatibility includes Johnson/Evinrude 6, 7.5, and 8 hp 2-stroke from 1980 with the relevant pin-drive gearbox. Product-specific engine tables also include 4 hp 2-stroke from 1980-1983, 4.5 hp Deluxe 2-stroke from 1986-1995, 5 hp 4-stroke from 1999-2003, 6 hp 2-stroke from 1986-2005, 6 hp 4-stroke from 1998-2003, 7.5 hp 2-stroke from 1980-1983, and 8 hp 2-stroke from 1986-2005. Engine power alone is not sufficient for selecting a propeller; the year, full model number, gearbox, and shaft type must also match. Certain engine variants, including 8SRL and 6SL in the relevant model group, use a different propeller.
Replaces OEM numbers
The propeller cross-references to OMC/Johnson/Evinrude OEM no. 390237 and 0390237, as well as BRP/Johnson/Evinrude OEM no. 778797 and 0778797. OEM no. 0390237 has been superseded by 0778797. Michigan Wheel 012032 is an alternative cross-reference in the same size and engine group.
The propeller is mounted on a suitable propeller shaft with a drive/shear pin. Drive pin, thrust washer, nut, and cotter pin are not documented as included parts. Therefore, check existing mounting hardware and the full engine model number before installation.
Always check the engine/drive model and original part number before purchasing.
