I used to have a 17 ft. alumn. canoe that I used for about 6 years that was rigged up for fishing and it gave me great results, the only reason I sold it was because I got married again and I needed a bigger boat for the family.
Rigging the canoe: The way I had this canoe rigged up was with a 27 pound thrust electrical trolling motor and a good sized deep cycle battery. I found no need for buying a motor mount, I just used a 1/2" thick piece of construction plywood to reinforce the side of the canoe and clamped it to the back side of the boat. I bought two strong clamp on rod holders, one for each side of the canoe and used 6 ft. med. fishing rods with green 14 test fishing line with big reels for lots of line for trolling and a good fight. I also had a low budget Eagle fish finder on the boat, I connected the skimmer to the electrical trolling motor using a adaptor. A large well charged deep cycle battery at speed 3 using a 27 pound thrust Mini Kota electrical motor should give you up to 5 hours of trolling time, wind will cause you to use more power (speed 4) so take that into account, take two batteries if you plan to be more time.
Fishing method: I always kept a good assortment of floating/deep runner Rapala lures, Shad Rap were the best producers. I would first study my fish finder to find out at what depth the bigger fish were hanging out at, then I would I check out my assortment of lures according to a chart I had about the info of the depth of each lure and put the right lures, be it a deep runner or a shallow runner on the fishing rods for that depth, the lure should pass over the heads of the fish for them to see it, not under them for better results. Then I would use a Shad smelling fish attractent with amino acids on the lures, I would then place the fishing rods into the rod holders in front of me and let out at least 100 ft of line behind the canoe to troll around all the hot fishing points in the lake using speed 3 on the motor for a good action on the lures.
Results: The electrical trolling motor is silient, the canoe also cuts water silently, catches even the most wary fish off guard. There were days when no body else caught anything in the lake and I would come home with a 5 gallon plastic paint drum full of fish. It is common to catch 3 to 4 pounders (Large mouth bass) with this method, just make sure you have your drag set right so that the when the big ones hit they don't break your line.
Another good fishing method I used from time to time with white plastic curly tail jigs was bouncing the jig off the bottom when the fish were really deep, I would use a slower speed 2 on the electricial motor, in this way the battery lasted longer. I would just troll at speed 2, and raise and lower, let it hit bottom and slowly raise it again. I also used this method for salt water fishing, but using yellow plastic curly tail jigs with a metal wire leader and used to catch some real nice Snappers. Great sudden hits this way, what a thrill.
I hope this helps.
