## 🔌 Function

Turns the drive's rotation into thrust, the 19 inch diameter sweeping the largest disc in this 2-blade range and putting the heaviest demand on the engine.

## ⚠️ Common Signs of Failure

-   Engine held well below its rated revs at full throttle
-   Heavy black smoke and rising exhaust temperature under load
-   Strong vibration through the hull as speed builds
-   Revs increasing with no gain in speed, a slipping hub
-   Blade tips bent or a section broken away after a grounding

## 🛠️ Service Notes

-   A propeller this size holds the engine down if the boat is heavier or dirtier than when it was propped - check rated revs at full throttle before assuming the engine is at fault
-   Inspect the drive shaft taper and splines for wear and fit new locking hardware
-   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.
