ALUMINUM PROPELLER 9.9X10 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat through controlled rotation in the water. This 9.9 x 10-inch aluminum propeller works directly coupled to the engine's drive shaft, driving the flow of water backward to generate the necessary thrust. Its ten-spline design provides a secure, slip-free attachment to Tohatsu cradle engines, guaranteeing efficient transmission of the available power. Optimal propeller operation is critical to maintaining cruising performance, maneuverability and fuel economy; Any deformation, cracks or loss of balance significantly reduces performance and increases hull vibrations.

When to replace this part?

You should check the condition of the propeller if you detect abnormal vibrations in the rudder or hull, unexplained loss of speed, abnormally high fuel consumption, or if you notice deformations, cracks or dents in the blades after hitting bottom or colliding with submerged objects. It is recommended to visually inspect the propeller at the beginning of each boating season and after any impact; Aluminum is strong but susceptible to gradual erosion and mechanical damage in prolonged service. Preventively replacing the propeller when it shows signs of wear prevents excessive vibrations that can damage the drive shaft and other critical components, as well as ensuring maximum propulsion performance throughout the season.
