Trolling Motor Advice

[maldoro]

Hi all,

I have a 2006 Sundance B20 Skiff. it is pretty light for a 20 footer, weighs about 2500lbs. I want to get back into bass fishing and need a trolling motor. In my searches, it suggests a 24volt motor to pull this size boat around. I have two opportunities to purchase a used trolling motor. The first is a MinnKota RT65 with auto pilot for 350. The second is a MinnKota bow mount hand trust with 55lb of thrust for 175. Both are in great condition. My issue is I have two batteries on a switch for starting and all electronics (live well, radio, fishfinder/gps, washdown, etc...). I would prefer the 12volt motor with the hand control, but concerned that it will not meet my needs. I'm relocating to Georgia, so this will be used in lakes. If I go with the 24volt system then I need two additional batteries. I have no idea where to mount these. Curious what some of you have done with your setup. Thanks in advance for your assistance.

Re: Trolling Motor Advice

At 2500# you need a 24 volt motor period. Any breeze at all and a 55# would need to run wide open to maintain position. Since you are cramped for space, you will need to make some modifications to add at least one additional battery. The stuff you have on the current auxiliary battery are not high-current draw items and some of those (locator, radio, and even the washdown pump) could be operated off the starting battery. You might even consider replacing the starting battery with a large capacity marine starting/deep cycle. The new battery and existing auxiliary battery can then be used in series for the 24 volt troller. You would need to disconnect both troller batteries from the switch as you cannot place a 12 volt alternator across a 24 volt system. To charge the batteries, install a two or three bank on-board charger and plug in at the dock. The engine will keep the starting battery topped off with no problem.

I really couldn't pass up the 24 volt motor. Too good of a deal plus I have the option of installing the co-pilot later. Thanks for the advice on the batteries. I think I will just leave it as is. i like having the additional starting battery just in case. I have a new deep cycle battery that I bought for my popup. I will buy another and probally mount them in a forward compartment. I remove the batteries when not in use so no need for the onboard.
