This Polastorm Yanta aluminum propeller for Tohatsu/Nissan 40–60 hp is a 3-blade, right-hand rotation propeller for outboards with a 3¼" gearcase and 13-spline propeller shaft. This variant has a diameter of 11 5/8" and a pitch of 11".
The size specification 11 5/8 x 11" describes the diameter x pitch. The pitch indicates the propeller's theoretical forward movement per revolution before slip and must be selected in relation to the engine, boat, load, and desired RPM.
The propeller is made of aluminum and has three blades. The aluminum alloy is A356-based and infused with strontium, magnesium, and titanium. The construction is manufactured using APC precision casting, heat-treated, and finished with a robot-applied, corrosion-resistant powder coating.
The pressed-in rubber hub transfers power between the propeller shaft and the propeller. The hub is designed for a 13-spline propeller shaft, and the propeller rotates to the right. The 3¼" gearcase specification is a compatibility and mounting dimension, not the outer diameter of the propeller.
The propeller is designed for Tohatsu and Nissan outboards of 40, 50, and 60 hp in both 2-stroke and 4-stroke versions. The engine's gearcase, spline count, and original propeller reference must match before installation.
OEM and cross-references
The propeller replaces Tohatsu OEM no. 353B64103-0, also written as 353B641030. Documented cross-references include Polastorm 3157-3117-11, EMP P5311-1163-11, Solas 5311-116-11, Michigan 142405, and Turning Point 21301410. Cross-references should be used in conjunction with verification of hub type, dimensions, and the engine's original propeller data.
Always check the engine model, gearcase, propeller shaft, rotation direction, and original part number before purchasing.
