    Thumbs down Finally tested a tweaked 15/20R prop in my ski

    Last night i tested this prop in my moded stage II + RXT, to resume my testing if you own a big and heavy 3 seater ski like mine please DON'T WASTE YOUR TIME AND MONEY with this prop, the ski was a complete DOG from the hole the midrange power was TERRIBLE and i lose almost 2 MPH in the top end vs the Impros repitched 14/20, my best top end speed was only 71.5 MPH @ 8000 peak rpm's with the glove box in and 8050 with the glove box out, i would only recomend this taller prop to people with a MONSTER engine like Jay (Red Devil) otherwise keep away from her.

    I thought everyone using the 15/20 had an RXP I do not see how it would work on an RXT.

    Well i tested this prop in my ski cause my riding buddy was bangin the rev limiter with her in his stage II RXP with his Less Cooke "B" SC set-up and i thought that it was gonna work fine in my ski with my mods but i was wrong... any way i don't spend a cen't in this test since the prop is not mine

    Level 1 from Scotts performance

    14/19 SOLAS
    HIS OWN CUSTOM AIR INTAKE
    2.5degree pump wedge
    and power pipe from Rotax racing
    and a good rider that knows how to get speed out of the boat


    We have built a couple of these boats and they fly

    My moded stage II RXT run 72ish MPH @ 8450 peak rpms with my tweaked 14/17R solas prop any day and any time with blistering accel in back to back runs on mid 80 to low 90 deg air and ran 73 MPH @ ***8150*** rpms with a Impros 14/19 repitched to 14/20 spec's so i know EXACTLY what is the prop that i need, this next Monday i will place and order for one since the one that i tested was not mine (with 2 mm pulled in the trailing edge) to gain another 200 or 300 rpms more and i am sure that i would break into the 74 MPH zone with her hands down with my current set-up

    15/20

    Guys,


    99.9% of the boats on the water cannot handle these props. Who ever said you need monster power to run a 15/20 is right. Basically full Stage III's need this prop for red-line reasons. The boats that can turn this prop have huge low-end torque and massive power all along acceleration curve. If the boat can push it though they are said to be a wonderful investment.

    I had one with the old ecu and ran it at 8400 in 4 -1 hr. races with 20 ski's chasing me the whole way You do not need monster power. Take 50thou. out of the leading edge... DO NOT do much to the tail.
