92 GTS help rev limiter

[hardtarge]

OK I know wearring wearrring wearring.

92 gts starts fine issue is 3/4-WOT sounds feels like i'm bouncing off the rev limiter same noise if you spin it out.

there is no loss of top speed. or noticeable acceleration change.

same speed and acceleration as our 93 GTS same engine noise/pitch at cruise/acceleration only difference is on the 93 3/4-WOT yields not more speed maybe a little deeper growl.

so what can I look at? MPEM/rev limiter? Impeller/wearring? or carb rebuild?

MPEM taking the ski out of storage last week needed to open the brain box to replace the 15amp bullet fuse. other then fuse holder was a little melty it looked really clean no water evidence. (this is the old mpem with 2 relays)

92 GTS... what is the compression on the old tired seadoo...it should be at 150 psi idealy.

ski is 300 miles north of me no clue. it starts pretty quick maybe 1-2 sec and running. so suggest enough compression move a good amount of air.

I don't completely understand the carb or the mpem.

is there anyway to gerry rig a tach to a ski like this?

what order of tossing parts up would you suggest?

wearring first?

pull the carb apart?

swap mpem's with the good running ski?
