gp1200r .... modd'd .. what prop should i be using...
My ski is a 1200r stock weisco piston , ported jugs wave eater clips reed stuffers , f/a , jetted carbs, d plate stock exhaust , premix oil 36:1 ams oil... r&d heads ( going on this weekend) i have island mod 4 plate with a 13/19 prop on it now .. was thinking about going to a 14/20 ? what i notice a big diffrence? I'm more worried about top end then bottom... I got the ski on the fat side right now and gotta turn the t handles a little more n lean it out but its got killer mid range to top end power.. Just looking for a little more up top.. Thanks.

looks like you have the mods to turn a 14/20 dynafly, I would upgrade to an 05 and up pump and try that... pending your rpms from the 13/19 as suggested by WFO first.
