well, you can install your trolling motor to your kayak...
problem solved....
besides the stearing part, then you will need to install a rudder system (which mine already has).
I will be installing my trolling motor to my kayak sometime and see how it goes, iv seen it done and apparently works like a charm.
I currently use the anchor system for bass fishing - major disadvantage, limits you big time.
Will post pics once i have eventually rigged my yak out with the trolling motor in such a way that i can take it off for when i go to sea...
Watch this space in months to come (yea time is a factor, id rather be fishing that modifying the yak, lol so come winter, then il be doing lots on it.)
