Does this mean you can link two trolling motors on the transom? If so is it also possible to control them from a console also. I am about to buy the first motor for an all electric rig and would like to know if I need to get a certain one to be able to do this. 110# of thrust would be nice over the 55# I was planning to have.
Sorry I know there's a forum for motors but I searched it I swear! :wink:
I'm not a boat expert, so I can't tell you what parts to buy, but I can tell you what you can do to setup two 55 lb trolling motors in the back:
1. Get two transom mount trolling motors and mount them on the transom. You'll need to pay attention to where they're located and how they're aimed, so one will not pull to one side more than the other.
2. You wire the two trolling motors to 36, 24 or 12 volt relays (voltage controlled switches). This voltage controlled relay/switch allows you to use a low voltage/ampere signal and smaller wires to control power feeding from a much shorter run of higher current/larger (and much more expensive) wire coming from your batteries.
3. Depending on your needs/desires related to operation time, voltage requirements, etc., you'll need a battery or two (or larger capacity batteries) for each trolling motor. High voltage means a lower current draw, but again, more batteries.
4. Once you have the relays wired, you can control from the front of the boat with a single (or more if you choose, but why make things complex if they're not needed?) switch. I'm not sure what's available boating wise, but it could be a flip switch or it could be a foot operated switch (I'm guessing these are available). You'd have to ask someone else for the name/part number of these items.
5. Finally, you run the control switch voltage from the battery(s) you use to operate the front foot controlled trolling motor. The foot controlled motor up front is what you use to steer the boat with and the fixed rear motors provide addition thrust.
Notes: Depending on the size of your boat, you may not need two rear trolling motors. I suggest trying a single 55 in the rear and see what that does for you first, then go to 2 motors if you're not satisfied with. Some folks have several 55's and some folks have gone to some of the larger electric motors available now.
But remember, there's no free lunch. The bigger the electric motor or the more motors you use, the more batteries you'll have to have. At some point, the weight gain and cost will offset much of the gain in performance. I'm guessing somewhere around 5-6 MPH is probably about max from an efficiency standpoint. Anything above that and you're probably better off getting a small gas motor if the lake allows it.
I hope this helps.
