Reply To: Homemade OMC Starter Junction Box ideas?

[Don]

Are both engines going to use a 12volt system? If so, you may want to consider deleting the junction box altogether. All that is required is finding a place under the cowl to mount a solenoid. Then, you could just find an old black/red plug boat harness with the battery cables and hard wire it up under the engine cowl. Simply cut off the plug and strip the harness back enough to allow for ample lead length to fit both engines. The older RD does not have a stop circuit, the newer 35hp does, at least I think it does. You would need a key switch with two “m” terminals for the newer engine if your mag plate has the stop leads. You would simply not wire these two leads to anything on the older engine. This method would allow you to have a key/choke switch at the dash, I’m assuming you are using remote controls and a steering wheel….
Just a thought….D
