| Hi I am upgrading my trolling motor to a terrova 80 lb, replacing a 55 lb power drive. Going from a 12 volt to 24 volt system, is my current wiring going to be sufficient for the increased load. I have a 2002 tuffy esox magnum with factory installed wiring. I tried the search feature but couldn't find any info on this. Thanks Dave |

Location: Sun Prairie, WI | someone correct me if im wrong but isn't the load the wires see actually smaller with a 24v vs a 12v system. The higher the voltage the less the amperage draw? |

| Thanks Steve I didn't think I would have to ,but good to hear from an expert on the subject. |

Location: plant earth | not so much according to ohms law. lets say 12volts 1 ohm= 12amps. now just do the same 24volts 1ohm= 24amps. im not being a smartass either just dont want to see someone use a smaller conductor and have a possible fire or damage to equipment or themselves. |

Location: Eastern Ontario | I'm kind of in the same position as Haney and want to upgrade to an I pilot on my 17 foot tin bass boat. My 55 pound thrust has always been adequate and rarely run at more than 50%. So now the question should I stay 12 volt 55 pound I pilot with 2 batteries in parallel or go 24 volt 80 pound I pilot with 2 batteries in series. What are the pros and cons of each? What would give me the longest running time? My wiring is heavy enough for either. |

I don't know what your Tuffy has, but you should have 6 gauge wire whether you use a 12, 24 or 36 volt trolling motor.
If your boat has smaller wire, replace it.
Get the 80 lb. you wont be sorry. |

The only reason I can think of to get the 12 volt is if the boat doesn't have room for two trolling batteries. |

| Your Tuffy will be fine with the 24 volt system. The 80lb at 24 volt will be less current than the 55lb at 12 volt. Ohms law. |

Location: plant earth | Here's a chart. Looks like you need 8 to 6 gauge wire for max performance. If its equipped with that your good

Yes.
Yes, you change to the appropriate plug on the TM cable. I think the 12V is a maroon color. 24V plug is Black. |

Have to apply the correct formula. That isn't it.
24V TM will draw less current than a 12V version at a given thrust.
The wiring in a Tuffy is adequate for either 12 or 24V TM's. Make sure you have the wiring protect by properly sized fuses or Circuit Breakers.
