Location: Eastern Ontario | I want to change from a 12 volt trolling motor to a 24 volt Terova I pilot . I have space in the battery compartment for 2 group 27 batteries and will have to change the wire from 10 to 8 gauge.
Now the question can I run an accessory 12 volt socket off just one of the batteries I am thinking a spot light that wouldn't be run at the same time as the trolling motor?
If a 54 inch shaft looks to be plenty long is there any advantage or disadvantage to going with a 60 inch? The deck to the waterline at rest is about 32 inches.

Location: Mauston, Wisconsin | Q1- Sure go for it, that battery will be discharged more, and will affect the TM run time and take a bit longer to recharge. But, its not a problem for the battery.
Q2- Bigger waves.
Have fun!

Location: Davenport, IA | Disadvantage of a longer shaft is shallow water. It will either be too long to move around or sticking up and in the way. |

It is better to go to 6 gauge wire.
Yes you can.
get the 60", better to have more than you need than not enough. |

go with the 60" shaft and you will be glad you did when you are on rougher water. It won't be in the way as much as you think. |

Location: davis,IL | I did the same change a few years back. Went from a 12v, 50# to a 24v, 74 #.... the 12v had a 42" shaft... the 24v a 54" shaft. From personal experience I can tell you this... the 42" was too short...just enough in calmer waters... 18 to 20" chop and it would surface the prop. The 54" (Maxxum 74) is currently set at its lowest point without making a problem in its stored position ( i can still drop it about 10 - 12 "). From the standpoint of of 12 to 24 volts....incredible.... I'm not a big fan of running my bowmount (spooks fish)... but I can say that my 12v would last a day at best on the water. My 24v, I can go a couple of days between charges. For shaft lenth.... the 42" covered most situations o.k. but had its limitations. The 54" has been all I could ask for.... the only time I have to worry about the prop surfacing is in 3' + waves. The downside is the prop is a solid foot below the surface (6" below the keel) in calmer water and the head is still sticking up close to a foot on the bow of the boat. This is not a real issue when casting to the sides of the boat but does get in the way casting straight off the bow. For wiring... at the time when I did the change... somebody had a sale on 12', 6 guage jumper cables, I cut off the big clamps, soldered on the correct terminals and had my motor wiring...... Remember..... for this heavier is always better.

Location: Eastern Ontario | Ok so I bought the 24 volt Ipilot and 2 new batteries and am a happy camper. Before I buy an on board charger I think I will let my wife recover from the money I spent on the Ipilot and new to me boat.
I have 2 12 volt chargers can I just unplug the trolling motor and hook up the chargers or do I have to remove the wire between the negative on battery one and the positive on battery two? |

| I would remove the wire. Onboard chargers don't require this, but to be safe, I'd remove it.
I'd also advise going to 6 ga wire. As long as you are replacing the existing. Also, you're going to have to put a new breaker at the batteries. I'd go 60A. |

I agree with going to 6 gauge wire 10000000%
It's not necessarily cheap to buy 6ga marine wire but it's worth it. If you want to save a few bucks in this area find a set of 6ga jumper cables and lop off the ends and run those from your batteries to your motor. |

Location: WI | Not sure if all wiring is done like this but my boat is set up with a 12v/24v twist lock receptacle and plug for the trolling motor. There are two sets of #6 awg wires going to the bow. One set from each battery the 24v is derived from a jumper inside the plug. Meaning the batteries are not connected unless the trolling motor is plugged in. Thus the inboard charger is charging the batteries seperately. I would not suggest using any charger if the batteries are tied together. As for the gauge of wire use # 6 awg wire for sure. Voltage drop from a low voltage system can easily be seen in runs of as little as 15 feet with insufficient sized wires.
Take it for what it's worth but I am a Wisconsin certified electrician. |

| Guest, Minn Kota, Dual Pro multi-bank chargers have bank isolation, and can be used with batteries connected in series or parallel. No problem with either of these models. |
