Positive Locking Protection: Locks the prop nut firmly against the cotter pin assembly, eliminating the risk of propeller loss caused by high rotational torque or sudden reverse gear engagement.
Marine-Grade UV & Saltwater Resistance: Engineered from rugged, corrosion-proof polymers that withstand prolonged UV exposure, saltwater immersion, and physical impacts without cracking or becoming brittle.
Hydrodynamic Profile: Fits flush against the propeller hub to reduce drag and help shield the propeller shaft threads and rear oil seal from fishing lines and marine debris.
Fits Yamaha outboard motors featuring 4.75" large gearcases (V4 / V6 platforms) rated from 115HP to 300HP:
Yamaha 2-Stroke Series: 115HP, 130HP, 150HP, 175HP, 200HP, 225HP, 250HP, 300HP (V4 / V6 engines)
Yamaha 4-Stroke Series: F115, F150, F175, F200, F225, F250, F300 (V6 3.3L & 4.2L platforms)
PREMARINE Direct Replacement: PREMARINE provides high-quality aftermarket propeller nut caps manufactured to strict 6G5 dimensions, guaranteeing exact fitment over OEM prop nuts and cotter pins.
PREMARINE Quality & Value: Molded from heavy-duty marine composite materials with superior shock and salt resistance, PREMARINE’s replacement nut cap delivers reliable propeller retention and exceptional cost-effectiveness for Yamaha 115-300HP engines.
Cracked or Brittle Housing: UV degradation or over-tightening during propeller servicing can fracture the plastic cap, compromising its ability to hold the cotter pin securely. Immediate replacement is recommended.
Worn Internal Locking Splines: Rounded or stripped internal notches allow the cap to spin freely over the nut, removing its safety-locking function. Inspect during routine prop maintenance.
Missing Nut Cap: Operating without a nut cap leaves the prop nut and shaft threads exposed to severe oxidation and line-wrap damage, increasing the risk of losing the propeller entirely. Replace before next vessel launch.
