Stainless Steel Propeller HR Titan 3 13.9X21 Right Hand

Function and Technical Context

The HR Titan three-blade stainless steel propeller, with a diameter of 13.9 inches and pitch 21, converts the rotational torque of the drive shaft into propulsive thrust, serving as the final mechanical link between the powerplant and the water. Being manufactured from high-strength stainless steel, its structural rigidity minimizes blade deflection under load, resulting in more efficient power transmission and notably more direct acceleration response compared to aluminum alloy alternatives. Pitch 21 defines the theoretical advance per revolution: correct pitch selection ensures the engine operates within its optimal RPM band, avoiding both mechanical over-stress from excessive pitch and over-speeding from insufficient pitch. Right-hand rotation makes it suitable for standard single-engine installations with conventional transmission stern. It is a direct replacement for OMC part numbers 5033325, 5033329 and 0777026, as well as Suzuki part numbers 58100-90J20-019, 58100-90JC0-019 and 99105-00700-22P.

When to Replace This Component?

The clearest signs that the propeller requires replacement are abnormal vibrations transmitted through the shaft and transom, sudden loss of top speed or thrust from standstill, and persistent cavitation that does not disappear upon correcting trim. Propeller blades with nicks, bends or surface erosion from impact with submerged objects unbalance the assembly and generate cyclic loads that accelerate wear of shaft seals and gearbox bearings; therefore, any visible structural damage requires immediate replacement without waiting for the next seasonal service. Visual inspection of the propeller is recommended when hauling the vessel out of the water at the beginning and end of each season, and immediately following any impact with a submerged object: taking preventive action at the first sign of damage avoids transmission failures at far greater cost in open water.
