[QUOTE="dhoganjr, post: 354863, member: 12925"] If it's a 1/4" higher the height should be ok. How does the impeller look, has it been dressed (sharpened) recently and is it shimmed correctly. These 2 will make a big difference in getting on plane and top end speed. Also check the nozzle and make sure there are no rocks lodged between the exhaust tube and nozzle. I wouldn't intentionally try to hit the rev limiter, these computer controlled engines can go into limp-in mode if it is over-revved too many times. If it does this it will only turn about 2000 rpm's to protect the engine until you get it serviced. Have the fuel lines been replaced, if not the liners are more than likely ate up from ethanol and it will break up clogging filters, fuel pumps, etc. They will need to be replaced with the newer ethanol resistant lines. If any of this don't help, we'll go from there. [/QUOTE]
