place flow control valve from the pipe output after the Y over board right in front of the stinger.The valves need to be tuned to perform best,some are threaded adjustable,most are not. It is a important setting,it controls the pressure and amount of water flowing into the waterbox and pressure in the head pipe somewhat depending on the length of the hose coming from the Y to over board pisser. I have a non adjustable,I take it apart and stretch the spring to get the desired flow.I find it best to pull that line off and run the ski in the water against the dock and set it so that it only opens with top end throttle. then double check the water box after 5 min of ride time to make sure its just cool enough to not melt anything around it,
Running a dry box really helps low end response as well,not as much as having the right water setting on top screw,but alot. Most dont realize how much diff it makes.I actually use it as a quick detune for surf riding. along with a slight change to the bpipe top screw with the t handle screw,takes just a min.I remove the ball completely from the valve. I like a much more soft linear hit in surf to not get worn out as quick,also makes the exhaust 2x less loud for long rides. Cool little trick for dual purpose skis
mybad...you must have had way to much water going through your pipe screw settings before you changed it,this setting does not provide better top end performance than some other good settings for other purposes..but around here who cares about sustained top end right? Some people dont mind the delayed response with the trade off of more top end power. I personally hate it. IF the motor isnt responding at the precise same speed as im pulling the throttle... its not good enough yet !
