Exactly right! But remember, not all wood props are created equally. Torque will vary with the density of the wood type and thickness. The multi-laminate can be torqued at a much higher value than a plank prop.
Crush plates should match the diameter of the crank flange, or in the case of RVs , the extension. 7" is preferred over 6". Especially for 150HP and up applications.
In rain, as long as you have good leading edge protection, normal cruise settings are acceptable. |
