Thanks for the replies. I was wondering about just replacing it.
Also thought about buying one of the smaller 30 lb thrust ones. Thats what I had before and it worked. Did the job and a little easier to manage size wise on the boat. The 50 was just a lot nicer in wind, going low and slow, and getting through the lily pads.
But if I got a 30, I could spend $100 and then tinker with my current 50 in my spare time.
