Yesterday, The Watercraft Journal took a bit of a detour into an offshoot PWC realm, introducing the Inkfish runabouts – electric Radio Controlled (RC) jet skis that pack a lot of fun into slightly more than 14 inches of ABS with either a Pro-version brushless motor for under $150, or the value-model brushed version for less than $100.

Today, we continue the slight detour from normal PWC coverage – but with a $249,900 difference from yesterday.

A somewhat Frankenstein-ish (albeit a more handsome Frankenstein that Shelley’s) amalgamation of Yamaha runabouts and a Polaris RZR, the Typhoon is marketed as the “first Aquatic Utility Vehicle (AUV) ever made available to motorsports enthusiasts.”

The creation of Shadow Six Racing out of Jupiter, Florida, the Typhoon features custom built reinforced carbon composite racing hulls that house twin four cylinder supercharged Yamaha GP1800 SCHO R engines. The upper portion of the Typhoon is constructed from aerospace grade titanium and carbon fiber.

Specs of the Typhoon include seating capacity of 1-3, a weight of 2,365 lbs, a 37-gallon fuel tank, a total length of nearly 11 feet (130 inches) and Bluetooth capabilities.

Of note, a quick delve into the details of Shadow Six brought three names to the forefront that many WCJ readers will be familiar with – RIVA Racing, Fuel Tech and Wamilton’s Customs. 

According to the Shadow Six website, “Shadow Six Racing is a group of brilliant minds working hard together to redefine impossible by leading the evolution of the motorsport’s world. Our brand is an outreach for our passion for precision, perfection, and performance aimed at building the world’s most innovative powersports vehicles.

Shadow Six Racing was founded by CEO, Ryan Goldberg after being awarded an initial patent on an invention called the A.U.V. or Aquatic Utility Vehicle. The A.U.V. was loosely based on the concept of designing a high-performance side-by-side vehicle which could retain or exceed its driving and handling characteristics, while maintaining a fully functional FOX 3.0 active suspension system capable of tackling extreme surf conditions unlike any other vehicle on the market.

The Shadow Six Racing team began work on an initial prototype vehicle with Michael Meives, a 50 year veteran in the automotive collision repair and custom fabrication business in 2016. His custom fabrication abilities, and experience in Trophy Truck racing while residing in Arizona allowed us to prove our initial design with astonishing results. However, there was still a great deal of improvement required in meeting the engineering requirements of such a unique vehicle.

This led to enlisting in the help of Wamilton’s Customs, an internationally acclaimed custom personal watercraft manufacturer, fabricator, and leading watercraft designer since 1990. With years of experience winning numerous World racing and freestyle championships, Wamilton’s Customs is our partner in designing the world’s very best race hulls.

We know at our core that it’s always better to always try to engineer products to be lighter, faster, and stronger in any project we undertake. As a result, we’ve partnered with RaceTech Titanium in order to ensure that our vehicles are manufactured with the most consistent and uncompromising quality products available anywhere.

RaceTech Titanium offers Titanium nuts, bolts, and custom parts for all types of racing applications from mountain bikes to top fuel dragsters. They work directly with many of the biggest names in the racing industry, allows them to bring the best technology available anywhere to the Shadow Six team.

Finally, we chose RIVA Racing to handle the performance enhancement aspects of our vehicles. Today, RIVA Racing spans over six different buildings in Pompano Beach, Florida employing over 100 staff members. These buildings include departments for Research & Development (R&D), Sales & Technical Support, 2 fully staffed Parts and PWC Warehouses, International Shipping & Receiving Departments, PWC Sales, PWC Service, and Private Test Lake facility.

RIVA Racing is recognized worldwide as the premiere source for personal watercraft performance parts and accessories built with the highest quality standards in mind.

Along with their complete line of RIVA Racing PWC Performance Products & Accessories, they offer specially modified watercraft for the serious enthusiast or racer. A strong line of performance products has helped the Racing Support Team as well as many others capture numerous National & World Titles as well as a World Water Speed Record.

Also, in March 2024, Fuel Tech became part of the Typhoon story with the installation and testing of the FT550 on the Typhoon.

Racing, recreational rides, endurance, fishing, family fun – No matter what type of PWC riding you do, choosing the right PWC is key. Several factors play into that choice, but some of the most common are reliability, speed and size.

Well The Watercraft Journal has a PWC to introduce today – and it definitely has the speed; from all indications, it’s highly reliable; and the size? Well, this is where you decide if size does matter when it comes to fun.

Introducing the UDI Inkfish – a sleek two-seater runabout with a coveted feature: a self-righting hull. In emergency circumstances – say for example, you take that corner buoy with just a bit too much throttle and the ski flips belly-up – with the single press of a function key, the Inkfish automatically returns to a stable, upright position.

Of course, the Inkfish is only 14” from bow to stern, so there’s that!

The UDI Inkfish is an electric, radio-controlled (RC) jet ski that comes fully assembled and ready-to-run straight out of the box, with a detailed scale realistic Jet Ski design with a hidden propeller for added protection against elements and crashes, an anti-collision rubber strip, and a high-strength ABS shallow V-shaped hull that facilitates effortless navigation in shallow and rocky areas, mitigating the risk of collision and entanglement with underwater obstacles.

The Inkfish comes in a brushed, or “Pro” brushless model, with both versions embodying cutting-edge features and superior design for an unparalleled aquatic experience.

This high performance brushless model, with the Inca Gold on Jet Black color scheme, features a dedicated ESC and receiver, making this model perfect for those wanting peak performance while being value conscious. The integrated liquid cooling uses an inlet on the bottom and pumps the water through the ESC, then through the motor, and out the upper rear of the hull. This ensures that your electronics stay cool even through the most demanding splash sessions. Other features include the dual protection system of low battery alarm and out of range alarm, as well as a high torque 9g integrated waterproof steering servo.

The brushed model, with the neon green on charcoal color scheme, includes a sealed ESC/Gyro/Receiver combo, powerful brushed motor, and 9g waterproof servo. These are laid out cleanly within the hull allowing for better weight distribution. The brushed motor is wrapped in an alloy tubing and features an inlet port on the bottom for water cooling. The water travels through the cooling passage and exits out the top right in the rear of the hull.

Be sure to check out the AMain Hobbies video that even includes a comparison run to test out speeds of the two models.Now, we at WCJ know that runabouts are not everyone’s cup of tea, so for all you sport class junkies, AMain Hobbies has you covered with the Kyosho Wave Chopper. This electric PWC was originally released in 2001, but the upgraded 2.0 model features modern RC technology and performance. A redesigned rudder, stern tube and motor mount in the 1/6th hull, and an updated rider figure are combined with the latest RC components to take this model into the next generation. Optimal torque from the G14L water cooled 550 class motor works perfectly with the large capacity Kyosho Speed House KA60-91W speed controller to deliver crisp acceleration and racy performance while reducing heat loss. Styrene floats provide buoyancy that make the hull unsinkable, even if it is not completely waterproof. The hull and rider are pre-assembled, so all you need to do is install four AA batteries into the transmitter, and charge the included NiMH battery and you’re ready to run.

(Apologies to the stand-up sector of our audience, we were unable to find any RC standups!

Kawi Performance (KP) owner Steve Ciervo is back with another KP video release, this time taking a closer look at Kawi Performance’s plug and play Speed Delimiter Module (SDM) that was released a little over a year ago. 

Created for the Kawasaki Ultra 300 and 310 (2011 to 2021) the SDM removes the traction control, which is essentially the speed limitation on the 300 and 310. The SDM does not work on newer models, but is invaluable for the models that so many are still riding. 

Ciervo covers the quality and the specs of the KP SDM that make it stand out against similar products – key being the plug-and-play aspect that removes the frustration of dealing with wires and wire connectors and heat-shrinking connections and all the other annoyances of non-plug-and-play options. 

As he points out, the KP model is simple enough to be installed one-handed. 

Additionally, the KP SDM only works when the dash is on and the key is in, so it will not drain your battery, and it’s completely waterproof, with a hard aluminum casing.

See the full details of the SDM from KP below, and be sure to follow along on one of Kawi Performances latest videos, and don’t forget to check out the other helpful productions by KP and Ciervo.

Developed to be the easiest, and safest speed limitation removal device on the market. By plugging this into your 300 or 310, it will remove all speed restrictions and traction control at full throttle. That means more speed and acceleration. This device stands out as the best in the industry due to its ease of installation and compact design. No need to pull pins out of the harness or have wires running to your battery terminals or diagnostic port. This device is hidden completely out of sight, tucked right beside your ECU. Simply unplug the ECU connector, and plug directly into our device. It’s that simple! Plug and Ride. Only works on 300/310 2011-2021
