tight as you can get it. take a rag and put over the prop and hold the prop while you tighten it.. as long as you dont put a pipe on the tool your using, your not really gonna break anything. just get it as tight as you can by hand. dont really know how to explain it any better
PS, dont forget the prop washer!!! i seen a few new guys that didnt have it on, thats kind of iffy.

Tight as you can get it? Gimme that 6 ft breaker bar... I'll pop the crankshaft right outa the case.
You'll begin crushing the wood props on a .40 size motor at appx 40 ft-lbs. (varies... because the wood varies)
If the backplate didn't compress... 10 ft lbs would be plenty.
The tightest you want... hand an average 14 year old kid the 4-way prop wrench (Du-Bro's or Fox's appx 4 inch versions) Have him crank as har as he can. That's as tight as you want to go. Ynd the 4-way to Arnold Schwartznegger... he could probably break something using 2 fingers.

can you not read>??????? or did you only read the first five words????
hes using a nylon prop, its not an exact freaking science here. you got to be pretty strong to crush a nylon prop with the prop washer..... let me tell you, i have tried to break them just to see and i cant do it with a combination wrench.. but i suggest you read all of my post before you jump to the keyboard. any info you give, i do not respect because of what you just said.
people still use wood props?? why? nylon is better.
