I'm having problems getting my 90 hp outboard to go slow enough for a good drift speed and would like some advice on which of the above to get. I have found that a 15-20 mph wind will move my 18 ft aluminum boat along perfectly. The small outboard motor would solve all my problems but is obviously the most expensive. The trolling plate sounds like a good idea if I don't forget to lift it back up after trolling. I'm not sure if the drift bag is enough to slow my big motor down, and it may prematurely tear the bag. Isn't the drift bag only supposed to be used for slowing down wind powered drifts? Also, it may be a hassle once you land a fish.
