[QUOTE="megalomaniac, post: 5570200, member: 2805"] I'm still struggling with my Minn Kota Riptide SP ipilot 55lb with giving me enough thrust. I have torn the thing apart, replaced seals and TM pin, and even checked the pulse width modulation with an oscilloscope which indicate its running perfectly electronically with a full 12v delivered to the motor. Armature and everything in the lower unit looks fine. Still only pulling 2.1mph on full speed on my boat, which weighs only est 600lbs fully loaded. That's fine if I'm fishing with no tide, but when the current is ripping in the bayous, I prefer to fish into the tide for a more natural bait presentation.upon retrieve. In a ripping tide, I'm lucky to pull 0.5mph against it. If there were an impedence issue in the wiring between the battery and the motor, id expect to trip the fuse breaker or get some seriously heated wires which isn't happening.... So im now starting to think, this is all I'm gonna get out of it. Simple enough, go 24v and use 80lb motor... BUT I can't afford the weight of a 3rd battery, nor can I afford to switch to 2 lithium batteries to save weight. I suppose I could wire the cranking battery and trolling motor battery in series to get 24 volts, but I don't like the idea of not having a dedicated cranking battery as my motor is an electric start. Doing some research, there are some opinions out there that going to the Kipowa 3 blade TM prop may give extra water displacement over my current weedless wedge 2 prop. Other reports say no, and may increase amperage draw reducing battery time. Any if you guys switch from a weedless wedge 2 to a kipowa 3 blade? Results? Any other suggestions for my TM other than take it to a certified Minn Kota mechanic? [/QUOTE]
