Dial in slower, more consistent trolling passes for walleye, trout, salmon, and kokanee with the Davis Happy Troller Trolling Plate, a simple way to cut speed and steady a bow-light boat when lure action and boat control need to stay exact. This trolling plate mounts to your outboard’s anti-cavitation plate and drops into position to reduce speed for better presentations, then lifts up to help stabilize the boat while cruising through changing water conditions.
