Paging Squirtin Thunder

[holorinhal]

Jim can You, explain to Me the differences in the different size impellers (A,B,AA,AB),and how they affect the performance of the boat.
Which impellers are better for racing vs.ski/pleasure.
I am still very confused about the whole impeller deal and I thought that You being a pump Guy maybe You could shed some light on the situation,for Me,as well as any one else that might want to chime in and school Me.Thank's in advance...........Hal

Starting at AA(largest diameter), work your way down to A, AB, B, BC,C and so on...the larger the diameter the more power it takes to turn a given RPM.
