Power aside, the boat does have manners, thanks to sea-Doo’s “intelligent” brake and reverse. By giving the boat’s computer brain access to an electronically controlled reverse bucket — and the pilot a brake lever — a driver can slow the boat in nearly half the distance normally required. The computer prevents the bucket from dropping so far as to send the driver over the handlebars. I found I could feather the brake to further control the stop. That same function also allows the RXT-X to mimic the gears of a traditional boat, starting in neutral at the dock and moving into forward, or reverse, via the appropriate lever.
