Hello I'm starting this thread a tad early so I can start gathering info and get help knowing where to look. Recently I ran into a fisherman that got sold 3 bum trolling motor's their really good motors and sell for $500-$1500. They are saltwater specific Minn Kota Riptide motors. 55lb, 55lb, and a 40lb. The 2 we need to fix are the 55lb thrust ones. The problem is there is no throttle control. Its either on full blast or off. He had it repaired by someone and they didn't close it up and left it unsealed so he could go in and repair the 2nd one himself and use the 1st as reference. Needless to say he's now left with 2 non working motors. Originally the 1 he had repaired worked so hopefully we won't need parts on one of them. If anyone has any repair manuals for a trolling motor or schematics of one please post them. I don't think brand really matters that much but something for reference would be good. I plan on going over there on Sat or Sun and will post pictures as were working on it. I know this seems to be a very common problem and hopeing we can get it running so we can start buying them broken and repairing them. So far I'm thinking its probably an ungrounded or broken variable resistor but who knows. It may have seperate resistors for each speed setting. Think about it if you can or if you have other ideas for me to check please let me know so I can get right to work when I get to his house. For tools I have a great iron, multimeter, and most common resistors and caps. Thanks and I'll keep you posted.
