Art,

Slow speed trolling with an autopilot on a small boat like yours can be
a problem on days where you have a bit of a sea, and wind, to contend
with. Now when you talk about slow speed I assume your talking about 2
to 4 knots. As the speed increases, and the boat gets bigger, it's less
of a problem. Your best bet is to ask people that have the same boat as
yours if they have had problems, what system they have and how fast
they troll.

Don't feel too bad, I've run some larger boats that have a problem with
this as well, they just don't run slow enough on two engines, you have
to troll on one engine. All it takes is one wave at the right time and
your back to manual fighting the boat. I've even seen them change props
late in the season (smaller wheel or less pitch) so they can slow troll
with both engines in gear. So if a system works OK most of the time,
your probably doing better than most.
