Overview

The Yamaha SX240 is a 23-foot 6-inch recreational boat designed for versatile performance and comfortable cruising. With a beam of 8 feet 6 inches and a shallow draft of only 16 inches, this vessel weighs 3,298 pounds dry and carries up to 50.2 gallons of fuel. It is powered by twin high-output 1812cc Yamaha 4-cylinder, 4-stroke marine engines, delivering a blend of speed, efficiency, and maneuverability.

Power and Performance

During testing, the Yamaha SX240 achieved a top speed of 51.4 miles per hour at 7,550 RPM, consuming 23.2 gallons per hour and yielding 2.2 miles per gallon, which translates to a range of approximately 100 miles. For cruising, two optimal settings were identified: at 6,000 RPM, the boat runs at 37.4 miles per hour with a fuel burn of 11.5 gallons per hour, prioritizing speed; at 5,550 RPM, it cruises at 31.7 miles per hour while consuming 9.8 gallons per hour, favoring fuel economy. Both settings provide an efficient 3.2 miles per gallon and an extended range of 147 miles. The SX240 planes quickly, reaching planing speed in 2.5 seconds and accelerating through 30 miles per hour in 4.2 seconds. Despite lacking traditional running gear such as props or rudders, the jet-drive system offers excellent handling, allowing the boat to maintain traction and execute tight turns without sliding or spinning out. Operators are advised to moderate speed during turns for passenger comfort. A 12-degree bow rise was noted during acceleration, but the design of the sheer line ensures unobstructed visibility whether seated or on the bolster.

Exterior Design and Deck Features

Yamaha has optimized the bow seating area with versatile cushion arrangements that allow customization of the seating layout. A hatch in the bow area can be opened and secured to block wind through the walk-through windshield, providing protection on cooler mornings. The port side features a spacious storage compartment that can double as a changing room or accommodate a portable toilet. The transom benefits from the low-profile jet drive engines, enabling a sleek patio-style rear deck with ample seating and the option to install a table, creating a pleasant social space. The low transom height facilitates easy gear loading and water access. Additionally, the self-draining cockpit is plumbed to drain directly overboard rather than into the bilge, enhancing convenience and maintenance.

Helm and Cockpit Layout

The helm station is designed for functionality and ease of use, featuring a clean layout with rocker switches and integrated circuit breakers for quick access. Instrumentation includes three gauges: a speedometer flanked by two smart tachometers capable of displaying multiple engine parameters. Engine controls are mounted at a 45-degree angle, which is comfortable when seated but can feel awkward when operating from the flip-up bolster, requiring some adjustment in hand positioning. However, this is mitigated by the inclusion of no-wake mode and cruise assist features, which allow for fine incremental speed adjustments via buttons without manipulating the throttles directly. The captain's seat is a wraparound design with swivel and fore-aft movement, complemented by a flip-up bolster for standing operation. On the port side, the companion seat converts easily from forward-facing to an aft-facing lounger, facilitating social interaction in the cockpit area that can comfortably accommodate up to seven people.

Engine Access and Maintenance

Access to the engine compartment is straightforward, with ample space for routine inspections and maintenance. The jet drives are easily reachable from the transom, allowing quick clearing of debris or clogs that may occur during operation. This design consideration enhances reliability and reduces downtime.

Conclusion

The Yamaha SX240 combines efficient twin jet propulsion with thoughtful design features that enhance both performance and onboard comfort. Its rapid acceleration, responsive handling, and fuel-efficient cruising options make it suitable for a variety of recreational boating activities. The versatile seating arrangements, protective windshields, and easy maintenance access reflect Yamaha's attention to detail in creating a well-rounded day boat. Overall, the SX240 presents a compelling option for boaters seeking a nimble, comfortable, and user-friendly vessel.
