MULTI-C ALUMINUM PROPELLER 11.10X14 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the engine power into forward or backward movement of the boat. This 11.10 inch diameter, 14 pitch aluminum propeller works in the marine transmission system, coupled to the engine output shaft through the gearbox or directly to the crankshaft depending on the type of propulsion. Its fixed 14-inch pitch determines the theoretical distance of advance for each complete revolution, decisively influencing the power, acceleration and maximum speed curve of the boat. Progressive wear of the blades, erosion due to cavitation or impacts against submerged objects reduces propulsive efficiency, causing loss of speed, increased fuel consumption and engine overload.

When to replace this part?

It is advisable to inspect the propeller at least once per navigation season, looking for radial cracks from the hub, deformations on the edges of the blades, galvanic corrosion or loss of material due to cavitation. Symptoms of a damaged propeller include unusual vibration in the shaft, scraping or metallic noise during acceleration, progressive loss of revolutions at full power or erratic behavior of the boat in a straight line. Preventive replacement after 5 to 7 years of intense use or after accidental impacts prevents costly damage to the propulsion shaft and ensures optimal performance during navigation.
