Anglers might find some of the best fishing action in both salt and fresh water when trolling at less than 2 mph, but most motors can’t slow to such speeds. The Happy Troller from Davis Instruments is mounted on the anti-cavitation plate and allows finer control of trolling speed while also enhancing a boat’s stability at higher speeds. A simple pull of the operating cable locks the plate in place behind the prop. A metal troller then blocks the blade’s propulsion, effectively slowing the boat’s speed while allowing the engine to run at the proper rpm. Additionally, the Happy Troller aids a boat’s performance even at higher speeds, as it can act as a stabilizer for smoothing out rough rides in choppy water.
