In most cases this would be a correct assumption. However, if the axle pin holes are worn a blade could "hang up" more in one direction of rotation than the other due to asymmetrical bias on the pin.

Oh..

Lasalle: do you or do you not have a folding prop on this boat???

Yes, see post 7... but it is probably a bronze folding prop.

Sorry Lasalle, missed that the first time.... SD was yelling at me!

I'm pretty sure your problem is indeed the prop. Try spinning it in reverse just before you go ahead, that usually deals with the problem. If the prop is badly worn (or the cheeks splayed) this makes things worse.
