    Testing svho pump in sho

    Ok so I have a 2010 fzs with a few mods including 160 mm pump and liner
    My son has a 2014 fzs svho with a reflash

    His prop was damaged badly when he bought the ski
    So he was going to try my twin prop in his ski
    But the new solas prop I bought did not fit my
    So we fitted it to his pump and swapped pumps
    Now my ski with his pump ran great
    Launched harder than than his and another sho with a 155 pump but same mods as mine
    And ran a top speed of 88 mph at 8,740 revs
    His seemed to hate my pump
    It didnít launch well with the twin prop
    And the rideplate was setup bad and it bounced to much at anything over 73 mph
    His ski stated to play up and cut out as well
    Not sure it was heat related or a fuel issue
    I know the svho pump has a larger cooling passage
    And am wondering if the smaller cooling passages in my pump caused his ski to get hot
    Has anyone else had any experience swapping pumps
    We will swap back tomorrow and test again
    But Iím not keen on loosing to much speed if the twin prop is slower

    I didn't think the water cooling line mines up correctly .

    I tested the twin prop in my ski today and lost 4 mph
    My son ran his pump back in his svho and could only manage 78 mph
    So he mustnít have the power to pull it
    Now Iím going to have to get an svho pump
    As they donít make a solas 13/18 for the sho pump in a 160 mm
    And once youíve had a taste of easy speed itís hard to give up
