The Scarab 255 goes in the low 50's. Larger boat than any Yamaha. Most 240/242 owners seem to hit around 50 mph or less with the occasional factory freak hitting over 50's consistently. With the new ACE engines coming out in the BRP boats they will be even better performing. Regardless I wouldn't want to drive any of these boats at those speeds in anything other than glass conditions. You'll just end up getting tossed around and guest looking at you like you're a mad man because they fear for their life lol.
