Two years ago, on a lake somewhere in Florida, I had my perception of speed completely rewired aboard a Sea-Doo RXP-X 325. You see, in the US, there's a 'gentleman's agreement' between personal watercraft (PWC) manufacturers and the Coast Guard that limits PWCs to a 70-mph top speed. So, performance PWCs will all get to the 70-mph speed limit, but how they get there is what they're playing for.
Sea-Doo just rewrote the playbook with its new RXP-X 350.
