Re: How to troll with my "new to me" boat?
I have the same boat, though an older model. I've been trolling for 26 years now using a 9.9 kicker with EZsteer and it works fantastic. We troll for bass in the shallows, muskies in the channel and with downriggers out in the Lake for salmon and trout. Thus, my speed ranges from about 0.5 to 2.5 mph and the gas fired 2-stroke handles all speeds without fail.
First off, I'm assuming you want to actually "troll", i.e., run the boat with lines out the back, as opposed to just move the boat around and cast out the side.
A sock is worthless. Sure, it'll slow you down, but you have little speed control with it. Regardless, I don't think you want to run a 4-banger all day long at idle speed. Maybe with a V-8 because it would idle smother, but I still wouldn't want to run it that long.
I've seen a few guys using electric, but I have no first hand experience. Are they quick detatchable? If not, I wouldn't think it would do much good for your high speed performance with the 135 running. Besides, the batteries you would need and all the time to recharge them would be a PITA.
I have a straight transom, so mounting a std. retractable bracket was a piece of cake. It CAN be done on one like yours but it would require some custom building of a bracket mounted on the top.
My 9.9 has about 600 trolling hours on it now and has run flawlessly. On a typical day in the lake we'll troll for 6 or 7 hours, with only a 1/2 hour stop in the middle to eat lunch.
