Prop Torque Setting

[RogerQ 0]

Any idea what the proper torque setting is for the bolt that holds on the prop?

Snug

I measure that by the maximum force I can apply, by holding the prop from spinning with my hand, and tightening with a normal combination wrench.

I think I remember seeing an actual spec somewhere and it was in the 20-30 ft/lb range

What he said. Snug but not tight. Unfortunately I have experience taking props off (and sending them out for repair). The nut doesn't need all that much torque on it. The prop is on a tapered shaft and is tightend further when engaged in forward gear.

I'd get it as tight as you can by hand. I also place a block of wood wrapped in a towel up against the hull to hold the prop from spinning when removing or installing.

Acme's instructions say 35lb.

BTW,

I always smear some anti-seize on the shaft.
