Overview

The Nitro Z18 bass boat is an 18-foot 8-inch vessel designed for serious bass anglers seeking high performance and speed. Powered by Mercury's new 150 horsepower 3.0-liter inline 4 Pro XS 4-stroke outboard engine, the Z18 aims to deliver improved torque, acceleration, and overall efficiency compared to its predecessor, the Mercury 2-stroke Optimax. This review provides a comprehensive evaluation of the boat's performance, design, and features.

Power and Performance

The Mercury 150 Pro XS engine powering the Nitro Z18 is based on a 3.0-liter inline 4-cylinder block introduced in 2012 but features significant enhancements. It boasts the highest displacement and lowest weight in its class at 456 pounds, along with the highest alternator output of 60 amps. Key improvements include transient spark calibration that increases torque by 5 to 7 percent for better acceleration, a revised gear ratio of 2.08:1 in the 4.8-inch gear case to boost torque, and four raw water pickups in the gear case nose cone allowing for higher engine mounting and greater trim flexibility. During testing with two people aboard and a full fuel tank, the Z18 reached a top speed of 60.2 miles per hour at wide open throttle using a 25-inch Fury 4-blade propeller. Cruising at 3,000 RPM yielded 25.7 miles per hour and 6.4 miles per gallon, providing a range of 231 statute miles with a 10% fuel reserve. The boat demonstrated quick acceleration, planing in 4.1 seconds, reaching 20 mph in 4.6 seconds, and 30 mph in 6.4 seconds. Handling was responsive with smooth sweeping turns at moderate speeds.

Exterior Design and Deck Layout

The Nitro Z18 features a beam of 7 feet 10 inches and provides ample deck space for fishing activities. Access to the boat is facilitated by a fold-up ladder located on the port side. The aft fishing deck measures 6 feet 7 inches by 2 feet 3 inches, offering generous casting room. Underneath the deck hatches are compartments housing the batteries, a 30-gallon divided live well, and dry storage with removable plastic tubs on either side. The forward fishing area spans 6 feet 7 inches wide at the aft section, tapering to 5 feet 2 inches forward, with a depth of 4 feet 2 inches at the forward aft area. This space includes a wastebasket and a 62-quart draining cooler that can be outfitted with an optional sandwich tray. Additional exterior features include four 4.5-inch pull-up cleats, cup holders, and tool racks mounted outboard on each side. The boat is equipped with a Minn Kota Maxim trolling motor delivering 70 pounds of thrust and controlled by a foot pedal, enhancing maneuverability in fishing scenarios. The Z18 is trailered on a single-axle unit with a swing-away tongue, carpeted bunks, and a motor support, making it a ready-to-use package.

Helm and Controls

The helm console is designed for ergonomic operation and comfort. It is topped with a windscreen and features an instrument panel centered around a 5-inch Lowrance Hook 5X fish finder. Flanking the fish finder are SmartKraft multifunction gauges, with the tachometer positioned to port and the speedometer to starboard. The steering wheel is mounted on a tilt hydraulic helm for adjustable driver comfort. The throttle and shift controls are conventional mechanical units, with a remote trim switch allowing the engine to be tilted up for trailering. The boat includes a master power switch adjacent to the ignition key that disables electrical power to accessories, preventing battery drain. Storage for fishing rods is conveniently located ahead of the companion seat on the port side, complemented by a rubber mat on the gunwale to protect reel finishes.

Additional Engine Features and Maintenance

The Mercury 150 Pro XS engine incorporates several practical design elements to enhance durability and ease of maintenance. The gear case includes low water pickups that facilitate higher engine installation and compatibility with jack plates, beneficial for navigating shallow waters. Engine mounts have been stiffened slightly to improve stability. The engine cowl features updated graphics and a streamlined profile. A maintenance decal is prominently displayed on the motor's side for quick reference. The alternator's 60-amp output is the highest among four-cylinder four-stroke engines, and the idle charge battery management system automatically increases idle speed to produce 20 amps when low battery voltage is detected, ensuring reliable battery maintenance.

Conclusion

The Nitro Z18 bass boat, equipped with Mercury's 150 Pro XS outboard, represents a well-rounded package for bass anglers who prioritize speed, torque, and functional fishing features. Its combination of advanced engine technology, efficient fuel consumption, responsive handling, and thoughtfully designed fishing spaces makes it a competitive choice in its class. The inclusion of standard equipment such as the Minn Kota trolling motor and a quality trailer further enhances its value as a turnkey fishing platform.
