If you follow up on our blog some of you may know of our appreciation for the Yamaha VXR, We compared it to the Yamaha GP1200R in the way that it is more than enough for your average rider. 1800cc, 180hp, and naturally aspirated for ultimate reliability, and last year they updated it with a completely new hull. While some were sad that it wasn’t as fast as the old model due to drag, but it handled significantly better, almost too good. This year we find out why.
Yamaha brings back the GP moniker with the Yamaha GP1800. Featuring a 160mm, 8 vane pump and powered by the 1800cc HKS Supercharged SVHO engine which was recently revised to 250hp in 2014 for the FZR. This engine is the best platform for modification due to being the biggest displacement engine and highest torque rating. In stock form Yamaha restricts the engine fairly heavily for reliability and legal reason, yet benefits the most from simple bolts on parts, However, this isn’t new information so what is?
It’s the hull. While the Yamaha FZR was a great ski, its biggest weakness was the hull, especially when compared to the Sea-Doo RXP-X. Around a race course, there was no comparison, that is until now. Like I mentioned earlier this new GP1800 uses the same hull as last years new VXR, with the exception that the GP1800 uses NanoExcel2 technology. This means even with the added weight of the forced induction equipment the New GP1800 comes under the VXR’s weight at 752lbs dry, giving it a great power to weight ratio. Now we keep calling it the VXR hull but in reality, it was designed with the GP1800 in mind when the Yamaha R&D team went to work on it. Unlike the FZR that used be great at sweeper turns but not so much quick banks like you would need in a buoy race, the GP1800 is. It’s clear that Yamaha was coming after Sea-Doo’s RXP-X and I’m sure it’ll prove to be a worthy competitor, and an enthusiast favorite!
And yes if you, if you had any doubt everyone’s favorite stand up was gone rest assured, the 2017 Yamaha SuperJet lives on!
Probably the biggest news since the Spark, actually this is way bigger. We’ve been hearing rumors since the last 800 SX-R Left the showroom, but this is official, Kawasaki to release a new 4-Stroke Powered Stand Up Jetski Later this year.
And here’s a spy photo was taken at Dana Point, a common place Kawasaki does there testing.
In other 2017 OEM News, while not nearly as interesting, but definitely unexpected, the guys over at Sea-Doo have amped up their Spark with a new “Trixx” version. This new version features a freestyle like “Up Trim’ VTS nozzle system for performing “tail stands” and hopefully back flips one day, as well as an aluminum height adjustable steering system. Blaster guys? The Spark is calling 😉

The shortest steering system available to date! The Jetworks Central Steering System(AKA C.S.S.) is 4 inches shorter than stock, putting the bars on top of the center pivot point, offering less flex and a more responsive and precise feel when turning, and because here at Jetworks, we ride salt constantly, we decided to not reinvent the wheel, and designed our system with bushing. This means no more rusty bearings, maintenance and incredibly smooth turning feel. Works with Yamaha & Kawasaki’s and includes all necessary hardware for installation.

Sea-Doo has been using the original Rotax 1503cc 4-Tec engine since 2002 slowly refining and massaging it over the years to get more power and improve reliability, but with more than a decade of use, their is no doubt it was time for an update.
The New Rotax 1630cc 300 Horsepower engine keeps the same SOHC 3 cylinder 100mm bore configuration but gains it’s displacement by an increasing the stroke by 5.8mm for a total of 69.2mm, but increasing the displacement 100cc does not create a 40hp gain but it does allow the engine to develop a stronger bottom and mid range power. The power gains come mostly from a new intercooler and super
The new Supercharger is actually smaller than the outgoing model but more efficient using a 32 blade compressor wheel and spinning faster at 47,000RPM. Sea-Coo even claims the Supercharger is maintenance free due to the improvements on the clutch system, composite style bearings, and using thicker shaft almost an inch in diameter.
Along with the bigger engine a new supercharger, Sea-Doo has made improvements on the Intercooler and cooling system making it 33% more efficient, a redesigned cylinder head, and improved electronics including the new style fuel injectors and ignition coils. All of these changes help develop 300hp.
Obviously if you plan on keeping it stock and only care about top speed, it won’t make a big difference since ALL PWC’s are have a restricted top speed (at least in North America) but after riding the new 2016 Sea-Doo RXP-X 300 and comparing it back to back with the out going 260 model, I can say the difference is definitely there especially out of sharp turns and in the mid range, but what this new Sea-Doo 1630cc really delivers is a better platform to build on when doing modifications for racing or all around fun.
Something to look out for is that for the past few years Yamaha has been dominating the Stock Class in closed course racing, but with this new engine in the RXP-X I think the competition is going to be closer than ever before!
