The impeller that I had in it was an agressor B.
Soooooooo.......Which kind was it? :hammer2:

I'm sorry....it's an agressor B not a Berkley B. Any suggestions?
What engine and how much cam?
check the shaft with a magnet. if it's ss, no sticky. if it's ss/alloy (hard), the magnet will stick.

If it is not a race boat, I'd start w/an AA. You'll have good perfomance and be a little more economical too by not turning a higher rpm.
If you find you want more rpm you can cut it to an A, but you might find that you don't gain any speed...only rpm (not always the case).
You have enough power to turn those impellers pretty good.
I'd stick with a Legend impeller. The quality is there to begin with.
If you find a used Berk SS impeller in good shape, that would be a good choice too.
