All those old OMCs had a bent shaft like that. For a good reason too. You notice that the shaft enters the trolling motor at the very front. If it were a straight shaft, and it went in the very front, it would fight you when you went to steer it. Now, with the bent shaft, it is as if the shaft went in the middle. If you draw a line straight down from the straight part of the shaft, on down to the motor, that will be where the turning point is. Therefore, you have better leverage, and can turn it with less force, when under power. I have a slightly older one, that I picked up a yard sale, that I am converting to a transom mount.
If you give me the model number, I can contact someone who can get the thrust, and the voltage, and I can find the year. They were pretty good motors too. Very simple design, and some of them (the black ones) are still sought after by many bass fisherman these days. If you do decide to "throw it away" I wouldn't be opposed to taking it off your hands.
I like the design of that boat - no bench seats to mess with. I see the inside of the gunwales have an aluminum box. I assume this hides some structure, but I would like to see another picture or two.
Jim pointed out throwing out everything that isn't usable. At this point, all I can see that is trash is the spare tire (your trailer has 12 inch tires, but that one there appears to be 10 inches - you can use a different size spare on a single axle rig, but that one appears to be a bit worse for wear anyway) and that crab net. The rust on the seats can be fixed with a quick brushing, with a hand wire brush, and touch up of paint, if the vinyl isn't that bad. I would go ahead and remove that blue carpet, and see what is under it. Even if you were planning on using it as is, you may find something that needs work, on the bottom level deck.
Your galvanized trailer appears to be in good condition. Did that come with it, or did you buy that separately?
Good Luck, and keep us posted.
PS, I noticed the Ga. registration numbers. Where do you live? I am in Cartersville.
