I have a 2003 17" sailfish. The trolling motor is almost done and starting to think about a replacement. When it was new the TM seemed to push boat pretty good. It is a motor guide 12 Volt 55lb. I would need to add a third battery to go with a 24volt system or just go with another 55lb 12 Volt. Looking for suggestions or maybe someone else with a similar size boat and what they have done.
This is going to bug me all night!
Why not take advantage changing technology and get a single 24V Lithium and save the space and weight of 2 lead-acid 12V?
Here is one option......there are others............... https://dakotalithium.com/product/dakota-lithium-24v-50ah-deep-cycle-marine-trolling-motor-solar-energy-rv-single-battery/
