Ok here it is Satch.
I was in a similar situation as you when I bought my boat in 2002. Paid cash for my boat and it left me with nothing left. I wanted to do the trolling Fall thing on Mile Lacs, but with the 135 Mecury Optimax I could not get below 2 mph.
I bought the Cabelas Hydortroll/Troll Plate Troll Plate
Is this thing ideal and better than a kicker, NO. But if your budget will not allow you a kicker, this will work for the mean time. This unit is $99.99. When I bought it I got a free $29.99 Driftsock with it. In the 3 years I had it I did go through a couple of them (3-4). Again here is where great customer service comes in (my theme for today). Keep your receipt, cause I was able to bring in the broken one every time and get a new one on the spot from Cabelas . To let you in on a little secret. I broke the last one last Fall and returned it this Spring and got my $99.99 back in store Credit . Not my original intention, but hey the consumer needs to get the upper hand once in awhile .
So I would suggest buying that one. I know this last year they redisgined it (maybe to make it stronger). So I would buy that one above, if I were you.!
PS. Make sure you pick up some extra shear pins right away, they are prett cheap.
