It depends on where you will be boating; any kicker will move the boat across a pond on a windless day.
During the maximum current, tide, and wind conditions that the boat might ever end up in:
1) Will it have enough power to allow you to maintain navigational control of the boat during the maximum current, tide, and wind conditions that the boat might ever end up in.
2) Will it have enough power to allow you to return to port
against the maximum current, tide, and wind conditions?
In other words I would want a larger kicker if I might ever be near the Golden Gate, Columbia River Bar, or the Great Lakes, then if I would only be fishing in a local freshwater lake, during the summer. Very few people ever go out thinking that this will be the day that their primary engine will stop working, yet we know it happens all the time.
I assume that you have already considered twins, and decided that a single with a kicker is right for you. If not, just
click here for a wide array of C-Brat discussion on the subject, as it has been discussed and rehashed many times over.
Best of wishes.
