Available for left-hand rotation in multiple sizes and pitches.

🔌 Function

Converts shaft rotation into thrust, the coarse 16 inch pitch on a 17 inch diameter suiting a boat that needs speed rather than pulling power.

⚠️ Common Signs of Failure

• Engine bogging down and unable to reach its rated revs
• Black smoke under acceleration as the engine is overloaded
• Vibration felt through the hull at speed
• Revs climbing with no gain in boat speed, a slipping hub
• Blade edges chipped or the trailing edges eroded thin

🛠️ Service Notes

• If the engine will not pull to its rated speed, 23478918 at 17 x 14 is the next step finer on the same diameter
• Check the propeller for balance after any repair - a coarse-pitch wheel out of balance is felt through the whole boat
