    Default I Was Thinking

    I was thinking that the thru hub, 11 X 18 were better, not sure. Here is a picture of an 11 3/4 X 22 thru hub cleaver.

    Keep in mind that we at hillmarine.net make hundreds of Custom Propellers each year. It just sometime takes awhile to figure out the propeller for your boat.

    i tried one of your 10 1/4 x 18p choppers that a mate loned me .it ran around 57mph @ 6350rpm on my slt boat with a 55 merc.i was thinking your 11x20p chopper would be a good on a slt boat.

    Default IS 55 Good?

    What RPM do you think you should run at? 2 inches of pitch is usually 400 PRM's. The 20 has been a POPULAR exchanged prop. I mean, people buy then want to exchange them for 18's.

    Anyone tried one of these props? Be interesting to see how bigger pitch/diameter choppers handle on thundercats...

    Unc Ron,

    Finally i've rec'd the propeller just today, the post office called me to pick up. Nice prop but a bit heavy maybe because of the extra 1 blade..hahahaha..

    Once tested will inform you...cheers!!

    Best regards,
