Hey folks,
My 2007 Sea-Doo RXT used to sound very deep and throaty with a consistent low rumble; it would consistently hit ~68mph out on flat water, accelerated great, hit 8k rpms, everything was good. End of last season, I put new oil, spark plugs, and a new display in and then winterized it. (Had to put a new display in because the old one was sunburnt and useless.) This year, I take it out and it start and runs fine(ish) out on the water, but now it has a higher pitched sound, and gone is the low, throaty rumble of the past... It gets out of the hole like it used to, but now I'm only hitting ~63 mph with ~7600 rpms.
Did my new display cause this? Not sure why I lost 5 mph and 500 rpms, and now my old girl sounds like a Sea-Doo Spark. Because it runs and isn't causing problems, I don't want to take it to a shop and lose out on prime summer. I just want to figure out if this is an issue others have when putting in a new display. With the new display, does it kick in a limiter or do I need to get the ECU flashed to get my performance back?
Some other notes:
- I had the supercharger rebuilt in the middle of last season. Put 10 hours on it where it sounded great and worked exactly like it was supposed to.
- Went into winter with fresh plugs, new oil, stabilizers, and new screen.
- Filled the tank with 93, no ethanol, 13 gallons (my poor wallet).
- Was hitting 63mph (GPS confirmed) on glassy water with the full tank and still hitting 63 later in the afternoon with a quarter tank. One rider (170 lbs).
- 0-60 mph time was about 6 seconds.
- Battery is entering its 3rd season. Stayed on the trickle charger all winter as usual. Fired up fine, no "12V low."
- Engine has 330 hours on it.
