Advanced Trolling Plate By Davis Instruments Slows Motors Down To Fish-Tantalizing Speeds

Having an additional motor aboard just for trolling can get costly. Mounting directly to an outboard’s anti-cavitation plate, the innovative Happy Troller from Davis Instruments is a much less expensive option that slows engines to the perfect fishing speed.

Installing in just 15 minutes, the unique Happy Troller locks down behind the prop, enabling unmatched control at trolling speed. In the up position, it helps stabilize the craft, reduce porpoising and cavitation and smooth out the ride in rough waters.

Intended for use in both fresh and salt water, the durable Happy Troller is constructed from the highest quality stainless steel and marine-grade aluminum. A clear, anodized aluminum finish protects against corrosion. Available in two convenient sizes, the large fits all inboards/outboards and outboards 50 hp and larger. The small is designed for motors 20-50 hp. Lil’ Fella is an option for motors below 25 hp.

    It works well and really helps to catch those Walleyes on lake Erie.
