If it is froze just take a small bucket or a empty pop bottle and pour water from the lake or river on it and it will un thaw. only thing is you have to pour more water on it after you move to get it back in the water but it keeps you fishing
I use pam on my ice auger, snow blower, shovels, blades, etc to keep them from freezing up. In the spring i always spray down the shaft of the troller with silicone spray.
Just unsure of spraying just anything on the plastic, I've used sprays on augers and what not as well-all are metal and I know it won't harm it, making a trolling motor shaft brittle or having dust and what not cling to it and chew shit up was my main concern, will probably give the silicone spray a shot
So Pam is the answer to a frozen shaft then? Sounds appropriate to me....I've known a few Pam's who probably couldn't unthaw a hotdog in a microwave....and then a few who didn't need the microwave! Ok, I've never actually met anyone named Pam.....might explain the frozen shaft.
