I dont think a 50 lb thrust is a good idea. The more thrust you have, the more battery power it will use, so only get what is needed. If you had an 18 ft fiberglass fishing boat, a 50 lb might be in order, but a 10 ft toon?? I had a 16 ft fiberform, and I used a 35 lb minn kota for a very long time. It worked perfect for kokanee trolling, and the battery lasted all day. good luck, Brian
