My Sea-Doo Switch came from the factory with a large decal on the base of the captain's chair announcing that a fire extinguisher is located under the seat. When checking under the seat, there is a mount but no fire extinguisher. The mount is molded into the base and restricts what size will fit properly, not just in diameter and overall height, but also handle style. When searching different sizes and styles for one that would work, this one turned out to be a perfect fit. Like the mount was made for it. Side note: This is in a 2024 Switch Cruise Limited. None of them come with a fire extinguisher yet have the misleading sticker saying that one is there.
