This Polastorm Megara aluminum propeller is a 3-blade, right-hand rotation propeller for documented Tohatsu and Nissan outboard motors. This variant has a propeller diameter of 13 1/4″, a pitch of 17″, and a 15-spline hub. It is designed for motors with a 4 1/4″ gearcase.
The propeller pitch indicates the theoretical propulsion per revolution without slip. For this variant, 17″ nominally corresponds to approximately 432 mm, while the 13 1/4″ diameter corresponds to approximately 337 mm. The correct combination of diameter and pitch must be selected based on the motor variant, gear ratio, load, and the motor's recommended RPM range.
Megara aluminum propellers are manufactured using APC precision casting in an aluminum-based hybrid alloy with strontium and titanium. The surface has a robotically applied, anti-corrosive powder coating. The design combines three right-hand rotation blades and a 15-spline hub.
Compatible motor models
Compatibility includes Tohatsu/Nissan MFS75A, MFS90A, MFS100A, MFS115A, and MFS140A as well as TLDI 70, 75, 90, and 115. In addition, the 90 hp motor groups from 1987–2001, 115 hp from 1992–2001, and 120/140 hp from 1988–2003 are listed. The OEM documentation for the corresponding propeller reference also includes the Tohatsu M60C and M70C.
The motor's gearcase must be 4 1/4″, and the propeller shaft must have 15 splines. Motor power alone is not sufficient to select the correct propeller.
OEM reference
The propeller cross-references to Tohatsu OEM no. 3HKB64536-0, which denotes a 3-blade aluminum propeller with an approximately 337 mm diameter and 432 mm pitch. The reference indicates compatibility and does not mean the product is an original Tohatsu spare part.
Related mounting parts
Related Tohatsu parts in the same propeller group include hub kit 3HK-64238-0, front thrust washer 3HK-64235-0, washer 345-64124-0, and cotter pin 951503-0325. It is not documented that these parts are included, or that all parts are required for every installation.
Always check the motor/drive model and original part number before purchasing.
