With the exception of a few, these upgrades are what the modding community has been doing for years.

[aaron-fauth]

These upgrades have already been done in the aftermarket for quite some time. Good for Sea-Doo to make these changes on the stock engine.

[Mike-Rxtx]

this is the most excited ive been for a new design in a very long time

I Already got 325hp+ with a 2017 rxpx 300 and stage 2 kit. But always good to see seadoo making improvements

[jasonmekush]

Big props to seadoo for addressing the aftermarket world. The better retainers / springs will keep the costs down of going over 85 reliably. Years ahead of kawis junk motor which needs constant belt tensioners / adjustment etc. I doubt yamaha will keep pace due to their lovely new target customers. maybee the " women who run the water" can help design a better higher hp motor.

I love these mechanical animations, especially after a few hot ones 😂😅

Question Kevin.

I’m picking up a GTR-X 300, getting some small stuff for it.

BOV a good idea? As I’ll be playing a lot on it. Debating between sponsons or bov.

Looks like a miniature version of the ProCharger Hemi in my race car!

[billy-bo-dilly]

Lots of great features, but the new ECU is going to be a problem with the aftermarket world and performance tuning. Unless you want to go with a stand alone ECU, like a Motec, this is basically a 69 mph machine.

[troyhunter]

the words detailed should not be used in a 2 minute long video... this is literally just seadoos promo video..

This inline triple four stroke with EFI uses Rotax Advanced Combustion Efficiency Technology to deliver 90 hp with excellent fuel economy ( up to 21.8 mpg, 10.8 L/ 100km ) and ultra low maintenance .
