Modifying Hand Controlled Trolling Motor to Console Throttles?

Hi,

I live on an electric motor only lake and have the old dual Minn Kota Neptune motor setup with the control module on my pontoon boat. Each motor is a 48 thrust. I have replaced the control module and have to keep having the motors rebuilt which is not cheap so I have come up with an idea but has left me with more questions than answers, so hope you all might be able to help...

I am thinking of replacing the dual 48 thrust Neptune setup and control module with two independent hand controlled trolling motors with higher thrust and extend the wiring to throttles on my console. The motors will just replace the other two so the steering assembly can be utilized. I will have to extend the wiring and replace the hand controls to two throttles. Anyone have any experience with this type of modification?

Any help or push in the right direction would be greatly appreciated. I may contact my boat guy but I know he won't be cheap and thought the more I knew about this the better.

If I have done a poor job of describing my plan or left out important details please feel free to ask any questions. I am finding a few things on the net but nothing like exactly what I'm trying to do.

Thanks!

Chris
