As if the fuel gauge doesn't move fast enough, who am I kidding, it's about time. :) The 255 with twin 300's...

I can confirm the single and twin 300 engines in the MY19 Scarab production. But, details are still in the process of getting released. I will post some updates as I hear.

WOW! That's an awesom news, thanks for the scoop.
Imagine 600hp in a 21 or 22ft jetboat ... that would be insanely fun.
Lakes will start to be getting smaller at that speed LOL!

No longer a rumour as I found this official confirmation on Boating Industry dated August 1st:

"BRP Marine Group has announced the release of its largest Rotax jet propulsion engine yet – the Rotax ACE (Advanced Combustion Efficiency) 300. The new engine is now available on Scarab jet boat models and Chaparral Vortex models."

https://boatingindustry.com/news/2018/08/01/brp-marine-group-launches-new-rotax-engine/

Also the same announcement on Power Boat World:

Other sources are also starting to chime in with the same news.

Just picked up my Chap Vortex VRX with twin 300's this weekend. It is a beast. Still breaking in so haven't tested to it's fullest.
Nice!! In the 22 footer.. even better lol. I have twin 300's in the scarab 255.

Some advice.. :) I took my boat out for the first time last week ( was bought from LA and had 1.8 hrs on it from some test rides at a Lafayette boat show and my test ride and another person that test rode it and couldn't get financing) . Break in on the engines is about 3 hours - my engines gave full boost at around 2.8 hours. You will definitely feel it when it happens. The engines all of a sudden just breathe and you feel the power.

So - I'd bring on the boat with you a small socket wrench that has the 1/4 inch socket and an extension ( for tightening the wormdrive type clamps that are on every hose on each engine). A hose blew off my port side blower rendering the engine to not make any boost. For anyone not experienced at this or understanding that it is not a big deal - they could freak out and think that an engine blew up or some catastrophic problem. When I had the clamps checked - there were 4 clamps in other areas that were loose. Now... if one of the small clamps that bring in water to feed the cooling process of the mufflers/exhaust - that could have been a much larger problem.. Once these clamps were tightened down and gone through - the engines run great and the boat flat out flys..

Curious to know if your engines below 5,000 rpms are far apart rpm wise. My two engines - when under 5k ( and yes the twin engines button is pushed on, and the Engine Synch button is on) the engines can sometimes be as much as 800 rpms apart. However- once engines go in boost, they are perfectly aligned and at same rpms.

Boat with 3/4 tank and bimini top up has gone 63mph on my lake - 87 degrees out and right before raining. I'd have to imagine yours at 22 foot has to be 250-300 lbs lighter maybe - should go at least the 63 if not 65 :)

The Cruise control works great, and all is very comfy. about only complaints that anyone can really have with this boat are the usual things -- loud engines compared to an I/O or today's new outboards, and the low speed maneuvering ( looking at the Cobra steering upgraded fins potentially to help with the low speed steering. That is really the main thing in these boats - the low speed handling is sucky even for the best most trained jet boaters. If it's windy - good luck keeping it straight. I'm hoping that the fins will really help that a lot.

Good luck and congrats man!
