Once upon a time there was a revolution in jet boats. Everybody was building at least one, and a lot of the power was supplied by Mercury. When Merc left the market, independent jet builders lost their source of power. Then, only motor-sports companies like Yamaha and Bombardier Recreational Products (BRP) remained in the fray, and in it, they made plenty of hay — it was, and is again, the fastest growing category of boats in the marketplace. Then BRP stepped out, dismantling its Sea-Doo boat production to focus on performance watercraft.
