STAINLESS STEEL PROPELLER 14.5x25 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat. This 14.5 x 25-inch stainless steel propeller works directly coupled to the engine's drive shaft, generating the necessary thrust by displacing water. The right-hand rotation design is calibrated specifically for Mercury engines from 90 to 300 hp, including Command Thrust systems, which require precision pitch and diameter to maintain drivetrain alignment and prevent vibration. The stainless steel construction guarantees extreme resistance in saline environments, preventing galvanic erosion and maintaining optimal power transfer from the engine to the water without losses due to deformation.

When to replace this part?

A damaged or worn propeller presents clear symptoms: excessive engine vibration at cruising speed, reduction in maximum revolutions without obvious cause in the injection, abnormal noise during acceleration or loss of traction during docking maneuvers. It is advisable to visually inspect the propeller each boating season, looking for cracks, deformed blades, erosion on the leading edges or impacts from submerged objects—these damages compromise hydrodynamics and can cause water to enter the transmission. Preventatively replacing the propeller when the first signs of wear are detected avoids costly emergency repairs at sea and ensures peak engine performance all season long.
