Supercharged Super Vortex High Output 1812cc engine
This amazing engine produces smooth, flexible power and features highly efficient cooling and air intake systems as well as strong engine internals. The 160mm Hyper-Flow jet pump helps turn that power into electrifying acceleration - and the Electronic Fuel Injection (EFI) gives ultra-smooth and efficient power output.
NanoXcel2®. Maximum strength - minimum weight
Made possible by Yamaha's unique materials technology, NanoXcel2® is an impressive 18% lighter even than our revolutionary original NanoXcel® - yet just as rigid and strong. So it maximises the exciting sports performance hull design of the GP1800 to deliver sensational acceleration, higher top speed and greater economy.
RiDE system (Reverse with Intuitive Deceleration Electronics)
The revolutionary RiDE system transforms your riding pleasure, bringing a new feeling of confidence, especially for sports-style riding. Simply pull the throttle lever on the right hand-grip to move forward and accelerate - pull the lever on the left grip to slow down or reverse. Yes, it's really that simple!
Electronic trim and clear, stylish instruments
The electronic trim system, with its 2 simple buttons by the left grip, offers complete control of trim position, on-the-fly. Just click the trim in as you pull a tight turn -and then trim out again to blast away at top speed. Clear indicators for trim, RiDE system and F-N-R positions are a feature of the stylish instruments.
Remote security with Low-RPM Mode™
This innovative system is an industry-first for Yamaha. One click on the remote transmitter button engages a special "L" mode (Low RPM) to limit top speed – ideal for controlled manoeuvring. For your security and peace of mind, pushing a second button disables the ignition.
Powerful graphics and great metallic colours
The GP1800 is a really sporting machine, with Yamaha's race-winning reputation around the world behind it, so it needs to look the part- and it does. With aggressive graphics and exciting metallic hull colours, a multi-tone textured seat and 2-tone Hydro-Turf mats, it'll make you feel like going out to fly across some water!
Spacious storage - thoughtful touches
When you're out there enjoying yourself, it's good to know you've got your personal gear stored safely away. So the GP1800 has generous stowage space, including a glove box with a bottle holder, a watertight compartment under the single seat - and there's a very handy bow storage space too.
A sporting heritage that shows
We know you like to tow things and people from time to time and the GP1800 makes it a real pleasure. We've fitted a strong towing eye, a pair of large integral rear-view mirrors, very comfortable Hydro-Turf mats and a soft-touch re-boarding step.
