This Polastorm Megara aluminum propeller for Tohatsu/Nissan is a 3-blade, right-hand rotation propeller for select outboard motors. The variant has a diameter of 13", a pitch of 19", and a shaft connection with 15 splines.
The size 13 x 19" indicates the propeller's diameter and pitch. The diameter corresponds to 330.2 mm, while the 19" pitch corresponds to a theoretical advance of 482.6 mm per revolution, without considering slip. The propeller is designed for the motor group with a 4 1/4" gearcase class.
The propeller is made of aluminum and is part of the Megara series. The construction utilizes Polastorm's titanium-aluminum-based material and APC casting technology, as well as solution heat treatment and artificial aging. The material data for this aluminum propeller family includes a tensile strength of 280 MPa, yield strength of 220 MPa, elongation at break of 9%, and a hardness of 89 HB.
Compatibility includes Tohatsu MFS75A, MFS90A, MFS100A, MFS115A, and MFS140A, as well as M60C and M70C. The relevant Tohatsu/Nissan motor group also includes TLDI 70, 75, 90, and 115, as well as 90 hp from 1987-2001, 115 hp from 1992-2001, and 120/140 hp from 1988-2003.
The propeller cross-references to Tohatsu/Nissan OEM no. 3HKB64541-0. The original propeller with this OEM number is listed as 335 x 483 mm, while this Megara variant has the product-specific size 13 x 19". The OEM reference diameter must therefore not be used as a substitute for this propeller's documented diameter of 13".
