2 Not recommended for fishing or applications that require holding heading while
trolling at low speeds or operating in rough waters. For applications that
require precise heading control, our higher-performance Reactor 40 models are
recommended. Compact Reactor uses a gear pump design with limited performance
relative to similar flow piston pumps. Not recommended for power assist
installs, engines above 150 horsepower or boats with more than 12-degree
deadrises. Mount pump within 6’ of the steering cylinder for best results.
