Swapping Mercury 35 hp for a Johnson 70 hp

[dedmisson]

Hi everyone, I am currently in the process of swapping the 35 hp for the 70 on a pontoon. My question is, I know I need an adapter for the wiring harness but where do I go to find them. I dont want to have to replace all wiring on both of the the boats, just adapt the plug in over. Thanks for the help!

You mentioned nothing about the year and model of each motor, but it doesn't really matter that much because I doubt you will find any type of a conversion kit. You may be able to make one yourself though, but it's probably easier to just switch everything over.
