    I recently bought a 79 sleekcraft tunnel with a berk jet and it came with some spare/old parts. I found the overhaul kit box and this is what it reads on the side of the box.
    Overhaul Kit W/Impeller B-6217
    Impellar cut a-2
    Wear Ring Size STD

    My question is what impeller do I have then since the first line reads B and the other reads A?? It is a 500 hp 502 and spins 5000 rpm. Sorry for the newbie question.
    Thanks for the help!!

    i believe the impeller cut "A-2" means its a AA cut impeller. the other num,bers i believe are just part numbers. a retailer/wholesaler would be able to verify this for sure.
    P.S. just for comparison, my 502 in the rogers 18 is pushing the berk A/B cut at 5000rpm at 81mph. although many veriables to consider in set up. i just posted for comparison reasons.

    "B-6217" looks like it's short for "150-B-06217", the Berkeley part number for the "A" master overhaul kit. A2 = AA impeller.

    Squirtin Thunder. Your "chart" is not right. Where or how do you get these numbers?
