Videos: Follow PWCMuscle’s Yamaha GP1800 Build

There’s no hiding it; the 2017 Yamaha GP1800 WaveRunner has got to be the most popular machine in the hands of tuners today. The responsiveness to modifications is uncanny, and the results coming out of several builders and tuners is staggering. We’ve already shared insane results from both Dean’s Team and RIVA Racing, as well as from GreenHulk and even privateer racers like Brian Baldwin. Best of all, many of these (and others) have taken to YouTube and various forums to thoroughly document their installations and results.

One such video thread comes to us from Joe Zammataro of Starting with a bone stock GP1800, Joe walks us through the very easy-to-perform mods that have radically improved his Yamaha WaveRunner’s 0-to-60 times gradually with every modification. Joe began with what many would consider one of the more difficult mods: swapping out the impeller for a Solas prop. The impeller is the Solas YV-CD-13/20.

Next came the installation of a Riva Power Filter Kit (RY13110) and Intake Manifold Upgrade Kit (RY12040-IMUK), all intended to greatly enhance the air flow to the SVHO motor. Additionally, listed in the graph below is the reflashing of the ECU with a RIVA MaptunerX – all of which helps push this Yamaha to a staggering 0-to-60 speed of 3.1 seconds. There’s still plenty left to be done, so make sure to check it out.
