NOTE: The weights given here are an average. Due to tolerances and repairs, we strongly recommend that you weigh your specific propeller for weight and balance purposes.
AIRCRAFT ENGINE STANDARD CLIMB CRUISE WEIGHT *
Grob 115, 115A Lycoming O-235-H2C 72CKS6-2-53 28.40 lbs.

* HUB NOTES

When Climb/Cruise propellers are recommended, the lower pitch (Climb Prop) can be expected to offer better take-off, climb, and high-altitude performance. The higher pitch (Cruise) propeller should be chosen only if take-off and climb are not critical.
These notes do not supersede Aircraft Type Certificates, A.D.'s, or Service Bulletins.
