# 2027 Kawasaki Jet Skis Feature Supercharged Engines for High Performance Kawasaki revives its market presence by installing 310-horsepower engines into agile watercraft hulls. - **Source:** [Popular Science](https://www.popsci.com) - **Published:** 2026-11-08 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/5b93956c-c211-41c6-911c-a3d92f3f5bff ## Strategic Engine Integration Kawasaki has adopted a muscle car strategy for its 2027 Jet Ski lineup. By placing a 310-horsepower supercharged 1.5-liter engine into the agile STX hull, the company aims to deliver its quickest personal watercraft to date. This design shift mirrors the classic automotive approach of pairing powerful engines with lightweight chassis. ## Evolution of Power The transition to high-performance watercraft began with the 1973 JS400, which utilized a 27-horsepower 2-stroke engine. Following the industry shift to 4-stroke engines in the 1990s, Kawasaki introduced a 150-horsepower powerplant in 1999. By 2007, the addition of a supercharger boosted output to 250 horsepower, eventually reaching today's 310-horsepower capability. ## Advanced Supercharger Technology The current 310-horsepower performance is achieved using Eaton’s Twin Vortices System supercharger design. This system, previously utilized in high-performance automotive applications like the 2009 Chevrolet Corvette ZR1, maximizes power and efficiency. The drivetrain further incorporates a 4-into-2-into-1 exhaust system with dual water mufflers to significantly minimize backpressure during high-speed operations. ## Electronic Performance Modes Modern riders can customize their experience through four electronically controlled power modes. Full Power Operation unleashes the engine's total 310-horsepower capacity, while Middle Power Operation limits output to 80 percent. Lower Power Operation restricts power to 60 percent, and the Smart Learning Operation mode provides a safer environment for true beginners. ## Precision Handling Features The STX 310 models include a 160-mm jet pump featuring a three-blade impeller optimized for peak acceleration. A thrust reverser system allows for steering capability even when the throttle is released or the craft is in neutral. Additionally, a Launch Control system automatically adjusts the jet pump trim to maintain optimal boat attitude. ## Practical Onboard Technology The STX 310RX features a 7-inch display panel providing real-time data, including supercharger boost levels, trim settings, and compass readings. A rear-view camera is integrated to assist riders in monitoring skiers or wakeboarders behind the craft. Furthermore, a one-touch 5-mph cruise control system simplifies compliance with restricted no-wake zones. ## Reviving Stand-Up Models Kawasaki is reintroducing stand-up models for 2027 with the SX-R 160 and SX-X 160. These units feature 160-horsepower naturally aspirated engines. The SX-X offers a fixed motocross-style handlebar, while the SX-R retains a traditional moveable design. Both models are priced at $11,999, targeting enthusiasts who value traditional, agile watercraft handling characteristics. ## Market Positioning Outlook By launching five new models for 2027, Kawasaki is aggressively attempting to regain its status as an industry leader. The focus on high-performance, supercharged machines serves as a direct effort to excite customers and differentiate the brand from competitors. This strategy emphasizes both technological innovation and the return of classic riding styles. ## Sources covering this story - https://www.popsci.com/technology/2027-kawasaki-jet-skis/ — --- _Summary written by Brifing from the original reporting.
