The three-blade and four-blade propellers appear to have nearly similar fuel efficiency criteria at low and high speeds. Nonetheless, four-blade propellers almost invariably give better fuel economy at mid-range RPMs. Our PolaStorm 4389-4130-19 has a 13-inch diameter, which boosts your boat, and a 19-inch pitch, which moves 19 inches ahead in one round. It is stainless steel, which is more resistant to corrosion and more critical than aluminum.
Key Features:
- Four-blade propellers almost always deliver a better fuel economy than three-blade propellers at mid-range RPMs.
- Made of stainless steel, which is more durable, corrosion-resistant, and vital than aluminum.
