Universal 3 blade aluminium propeller for easy replacement of the propeller engine. Universal boat engine propeller, just check the compatibility of the propeller with your engine by checking the list below, choose the propeller step and the associated hub (choose each propeller hub by clicking the link next to your engine). Propeller performance: Forged molding construction ensures that these propellers do not bend the blades thus improving performance. Fuel economy, speed optimization, faster gauge, improved driving and stability in corners. Vents for rapid deceleration Events allow gas to escape, reducing the water density around the blades during acceleration. This allows the propeller to spin faster at low speed thus improving its power. Angled Blade Angles Larger blade angles reduce the turret produced by the propeller, assist in the flow of the boat sterl and improves overall performance. Forged moulding for greater strength The manufacturing process provides excellent mechanical properties.
