Product information about the Polastorm Aluminium RH 4x10x7" Prop. 9.9-20 PK Stella (High Thrust):

This Polastorm Stella (High Thrust) 4-blade aluminum propeller is designed for Yamaha outboard motors in the 9.9-20 HP range. Designed for superior thrust and maneuverability at low speeds

The Polastorm Poleax Stella (High Thrust) Series has the following features:

• Large blade surface area & good acceleration.

•  

  Improved fuel economy at cruising speed.

•  

  Ideal propeller for replacing aluminum propellers.

• Large outer hub so that exhaust gases do not pass over the blades when reversing, which increases grip (no "aerated water").

•  

  Maximizes pulling power and control, ideal for heavy loads and maneuvering at the dock.

POLASTORM Aluminum Propellers : The innovation of aerospace technology applied to aluminum propellers has now become a reality. The propellers are manufactured using APC Casting. APC casting is known as precision casting for the aerospace industry, allowing for the production of aerospace-grade products with high density and physical strength.

The robotic powder coating line uses AkzoNobel's patented, corrosion-resistant powder that is environmentally friendly.
