best cheap mods for that ski would be 150 psi head (93 octane) .bore the jet
nozzle out to 86 mm .( improves bottom end and a little on top). a skat trak
custom pitch of 11.5/18.5 swirl prop will greatly improve the hole shot and mid
range.You will always be fighting the 140 mm pump in that ski and cannot
cheaply change it to the 148 mm 1100 pump.Good luck,a mildly modded 900 is a
bit faster than a stock 1100.scott
