1970 eveinrude 115 electric shift

[ArrowNaughtic]

I posted a last year about the shift issue on my '70 evinrude 115 model 115083 I finally got around to verifying that it is indeed the selector switch for reverse that is not working. When I had the lower unit apart this spring to replace the impellor I did a test on both leads to the seperate solenoids and each functioned properly. A couple weeks ago I had the control box apart and did my tests on the switches according to the Sealoc manual I had borrowed from the public library system and did indeed find that the switch itself is the culprit.

One of the replies was from biggpoppakdog and he had mentioned he installed a toggle switch to replace his defective switch bank and said it solved his issue. I am sold on the switch fix, but am not sure if I should be using a 6 pole switch or just a 3 pole switch. Most of my online looking so far has only shown 3 position switches with the ON - OFF - ON configuration. On a normal 3 pole switch wouldn't that mean that the center position would be my forward and nuetral or reverse woud be at forward toggle position or back toggle position?
I ask because no power to either solenoid the boat is in forward gear, power to the upper solenoid is nuetral and power to both is reverse.

On either of the toggle switched you mention, SPDT (3 terminals) or DPDT (6 terminals), the center position would indeed be forward gear.

The SPDT switch I dreamed up requires a diode, the DPDT switch designed by F_R does not.

Arrow, I can read your mind. You are concerned that it will go directly from forward to reverse without passing neutral, right? So what do you think happens when using the push button switch and the forward button is pushed and you push reverse without hitting neutral? Yes, OMC designed it that way and it was a marketing point.

Besides, the lower unit actually does pass through neutral anyway---just very quickly.
