Slowing to optimum trolling speed no longer requires a trolling motor, hard-to-retrieve drag buckets or line-tangling drift socks.  By blocking part of a prop’s thrust with an aluminum plate, Happy Troller from Davis Instruments slows down even large engines.

Mounted on an outboard or sterndrive’s anti-cavitation plate, Happy Troller locks down behind the prop by simply pulling a cable.  It enables trolling at a slightly higher rpm, helping to avoid the carbon fouling on spark plugs that can occur from extended low rpm engine operation.

In the up position, Happy Troller acts as a stabilizer.  On bow-light boats, it smoothes out the ride in rough water.  It also reduces porpoising and propeller cavitation.

Happy Troller can be used in fresh or saltwater, made from stainless steel and marine-grade aluminum protected by a clear anodized aluminum finish.  It installs in just 15 minutes and comes with stainless steel mounting hardware.

Available in two sizes, the large Happy Troller model fits all sterndrives and outboards 50 hp and bigger, while the small version covers outboards from 20-50 hp.  Davis Instruments’ Lil’ Fella Trolling Plate is Happy Troller’s little brother, designed for outboards up to 25 hp.  Happy Troller retails for $139.99 for either model.  Lil’ Fella costs $79.99.
