STAINLESS STEEL PROPELLER HR TITAN 3 14.3X22 LEFT

Function and technical context

The propeller is the final driving element of the transmission in an outboard motor: it converts engine torque into hydraulic thrust, moving the boat through the water. This unit, made of HR Titan 3 series stainless steel, offers much higher impact and marine corrosion resistance than aluminum propellers, making it especially suitable for boats that operate in demanding conditions or in waters with the presence of sediment. The 22 pitch and 14.3 inch diameter define the theoretical advance per revolution, directly determining the engine's operating point within its optimal RPM range; An inadequate propeller causes over-revving or lack of speed, with the consequent loss of performance, increased fuel consumption and premature wear of the drive unit. The left-hand rotation is intended for installations in which the shaft rotates counterclockwise, usually as a port propeller in counter-rotating twin-engine configurations on Suzuki engines.

When to replace this part?

The most common symptoms that indicate that the propeller needs to be replaced are: unusual vibrations in the engine foot, noticeable loss of top speed or planing ability, difficulty in reaching the manufacturer's recommended working RPM, and noticeable imbalance when accelerating. Bent blades or blades with eroded surface cavitation also compromise hydrodynamic efficiency even if the engine appears to operate normally. It is recommended to visually inspect the propeller at each seasonal maintenance and after any impact with submerged objects; Replacing it preventively in the event of minimal structural damage prevents damage to the shaft seal and the gearbox bearings, resulting in significantly more expensive repairs.
