There are now several builders that make jet sport boats with BRP power (same as Sea Doos).
Scarab, Glastron, Chaparral. I have reviewed them all at boat shows and I like the layout of the Chaparral the best. 20 ft one with 2 engines - only reason I like 2 engines is to avoid the crippling ride or tow home when the jet pump picks up a weed, stick or rope. Too bad none of them have the cleanout port like Yamaha. Yamahas are good but I don't like their layout bench in lieu of a co-captains chair in their 19.2.
Now if I only had the bucks to buy the Chaparral ....
