Should be the same as my 2006 RXT Supercharged 215hp.... same basic hull same engine and jetpump. ~68 to 70 mph in good water conditions (ie. no waves just light chop... a light chop is actually better than smooth as glass, the chop makes bubbles under the hull which "frees" the hull to go a bit faster), 1/2 tank of fuel and 1 average weight adult rider (~200lbs).
I went up to 68 mph last August just before my spark plugs gave out suddenly, and I still had throttle left I wasn't at WOT that was FAST I swear! I do have a Solas Concord 13/18 SS impeller and an Aquavein intake grate. All else is stock though. The spark plugs failed shortly after hitting 68mph, I have no idea why it really spooked me I thought the engine had blown up or something. New plugs solved the problem, though I wasn't able to ride it again until this past holiday weekend to confirm that the plugs were the problem.
Oh and I sealed the edges of my ride plate (using black silicone, smoothed flush with fingertip) and filled the ride plate bolt holes (with marine epoxy, smoothed flat with a paint scraper then sanded flush once hardened)! BRP doesn't do a good job with the ride plate installation for some reason it's very inefficient, those bolt holes are like HUGE and cause drag like little anchors. Sealing the ride plate and filling those holes helps improve the performance by ~1-2 mph.
