Solas New Saturn stainless steel outboard propeller is a 3-blade, right-hand rotation propeller with a diameter of 10 1/4″ and a pitch of 12″. This variant has manufacturer number 3231-103-12 and is intended for documented Yamaha and Mariner applications with a 3″ gearcase and 10-tooth spline.
The propeller is precision-cast in stainless steel and features the large blade area of the New Saturn series. The design is developed for all-round performance and good acceleration. Exhaust is directed through the propeller hub.
The hub is designed as a traditional, pressed-in rubber hub and therefore does not use a separate replaceable Rubex hub system. The hub designation in the mounting system is YB-RB, no. 170320. Original mounting hardware can be used, and the documented complete hardware kit has number 17032501.
