Sea-Doo, the BRP Inc. watercraft brand, and Senna Brand have launched the limited-edition Sea-Doo RXP-X Senna 350 under a one-year partnership honoring Ayrton Senna, with 1,991 units to be sold worldwide and pre-orders open now. The flagship personal watercraft (jet-propelled recreational craft) uses Sea-Doo's new Rotax 1630 ACE factory engine, rated at 350 horsepower, and the company said it delivers 15 percent faster 0-60 mph acceleration than previous models. Tribute details include Senna's signature, references to his three Formula 1 world championships, the phrases "Seek your truth" and "Born to win," a matching passenger seat, a Senna-branded cover, a numbered 1991 plate and a color scheme modeled on his racing helmet. BRP said the project is meant to connect the brand's performance positioning with Senna's legacy, while Senna Brand said the collaboration extends that legacy to a new generation on the water.
