What do you mean "rev limiter is engaged prematurely 4500 ish"?
Are you saying she revs fine on the trailer 3-4000rpms but out on the water she won't go higher that 4500rpms?
Did you recently disconnect any air hoses connected to the SC,TB,IC,WB just before,could be a boost leak and just involves tightening clamps all around..
Or any other work on the ski that we should be aware of just before you notice the prob?

revs great on trailer zings on up , you wouldnt know had a prob
in water rev limiter kicks in aroung 4500
nothing has been done to this thing its 100% stock
ill pull the rear seat latch/innercooler cover off and check hoses but that shouldnt cause rev limiter should it ?

Your rev limiter is not kickin in as stock is 7600,something is making you loose power or boost..
Look at your boost gage when you go WOT,if you see only 8-10 lbs not full 15-17 your losing boost somewhere..
Again did you change or do anything JUST BEFORE on your ski,any off season maintence or upgrades(IC cleaning etc) ?

Others would know better than I would , but Id check the sc belt make sure its
not slipping & maybe the plugs & inspect jet pump ..
maybe the blow off valve on the back of your intercooler could be stuck open ..? Possibility
