🔌 Function

Converts engine torque into thrust, the three-blade form giving smoother running with better grip astern than a two-blade wheel.

⚠️ Common Signs of Failure

• Vibration under way that rises with revs
• Engine held below its rated speed at full throttle
• Blade edges chipped, bent or eroded
• Line or weed wound around the hub
• Pitting and corrosion over the blade surfaces

🛠️ Service Notes

• Only 18 grams separate this from the 17 x 16 propeller 23478971 at 3.175 kg, so weight is no guide - check the diameter stamped on the boss
• Confirm rated revs at full throttle after fitting; a wheel this size will hold the engine down if the boat is heavier than when it was propped
• Fit with cone kit 23749222 and a new single-use lock washer
• Installation hardware for the fixed propellers on 110S, 120S, MS25S, 130S and 150S: propeller cone kit 23749222, which includes screw 23748333 and lock washer 23680979.
