    Default Damn I love American Turbine!

    Get this.... I swapped out some Berkeley stuff on my new-to-me cruiser with some American Turbine goodies I had lying around the shop from my old boat. I spun 100 more rpm WOT (4900) changing from an aluminum AA to an stainless A impeller, 100 less rpm for cruise speed (3300), and the boat needed much less rpm to get on plane from a stop. And I haven't even bolted a loader up yet! Here's the old and new setup:

    old:

    -Berk JG bowl
    -alum A2 berk impeller
    -place diverter w/ droop

    new:

    -AT berk-energizer bowl
    -stainless A impeller
    -same place diverter w/droop

    The AT turbine trim I had wouldn't work. I tried bolting it up, but the tiller arm is so much wider than the place diverter's that the setup just won't work without changing the steering a bit. It was binding the cable. Anyway, I bolted the place diverter back on and ran with it.

    I didn't get a GPS run yesterday since the water was pretty rough, but I did manage to beat a much smaller jet in an impromptu drag race....lol.
