    non ported v ported Q..

    for all you plate gods out there can you tell me how its possible for the sweet spot to move once ported/new prop..
    had a nice bit of sun and no wind so perfect conditions for us uk guys, once again i was running a bigger number(mph) full of fuel and as the tank dropped so did my speed ....i know i have to come down in plate height as i have been to far in angle before and recognize the synmptons...

    plate is set to my old non ported magic number...

    now ported and new prop fitted i need less angle can you explain why this is so...

    thanks as always ........

    ...............paul........

    I've had props change my handling setup if thats what your asking.

    Usually I set my fastest setup when its at 1/4 tank or lower, that way when I put gas in it the handling is better.

    must be the prop change then...must say this prop is right on it and pulls a lot harder.. ..thanks rich...

    77.8mph full of fuel and no holes filled yet....76.7 mph 1/4 tank....

    think plate will be better off down to the .980 area...

    Paul the faster you go the more the hull lifts out of the water naturally.
    .980 works for me at 75 on one ski, the other likes .920 at 82..Both with tabs.
    Equally as important as plate angle is making sure the plate is true with the hull on the left and right sides.
    Take a 4 foot level and measure plate height from the hull on the left and right outer edges and make sure they are within .010 of one another.

    Both my skis were .040 higher on the right than the left. Had to shim the right side down .040 to true the plate with the hull.
    The difference was dramatic....

    Hello Paul the faster you go the less angle is required.

    Duke what setting are you running your tabs with the less plate angle of .980

    I am like Paul plates at .980 with tabs at .120 (80.8mph)

    With less angle do you go less tabs i keep hearing it and trying the less angle but keep loosing speed confuses the hell out of me.

    Paul what impeller are you running now.

    Mine is around 900 to 920 with no shims in the R&D tabs. Some people like more angle and shimming the tabs.

    Thats with the FF plate Mike. Seems they can be pushed down further without losing much speed.
