I use the really poor man's kicker - a 5 gallon bucket hung off the back rolleyes With this I can troll my 25 Yami down to less than 1 mph, and it really works for sockeye, also springers on the Columbia. 'Course in my little boat if I really want to troll slow, like in a tailwind, I just use oars.

The fishing was GREAT! The catching could have used some improvement however........
