    it should be an 85mm with the HO pump

    if it says 67X on the side, its an 87mm
    60T on the side is an 85mm

    Thanks WFO mine has a 67x meaning 87mm , since i have the this one does it mean i have to go up a pitch or two on my prop . Will it run a 14/22 solas ? or will i get better results going back to a 85mm. Not realey after top speed as i jump waves .

    probably a 14/20 with the 85mm, and a 14/21 with the 87mm.

    I'd stick with the 85mm

    both are 5 degree, but look out for an 87 mm that has 3 holes drilled and tapped on both sides (holes for reverse bucket brackets)... that could be an XLT nozzle at 3 degree
