69 Johnson throttle switch repair/replace

[sstrudell]

Looks like the throttle switch on my 1969 55Hp Johnson is bad. (Part number #0383620 ) I'm having a hard time finding a replacement part. My outboard only goes in forward gear now.

Does anyone have a remedy for this? Is there a way to bypass the switch and improvise with another switch?

I would hate to have to buy a new control box, so I am looking at all alternatives.

(BTW...This is still part of a problem I've been trying to fix for the past month. I had water in my lower unit and thought this might be contributing to the problem. When I refilled my lower with fresh lube, the throttle worked fine...but water was still getting in.

I then had my complete lower resealed. The mechanic fixed that proplem, but the motor is still only going in forward gear. I'm suspecting it was something the repair guy did, since he broke something else while resealing the lower. Fed up, I'm back to square one.)

Before you go jumping to conclusions you need to find out if the switch really is the problem. There are a couple of ways to quick test it. Easyiest is with a jumper wire.

Connect one end of the jumper wire to the + terminal of the battery, and locate the blue and green wires going down to the lower unit. Start the motor (on muffs is OK), and touch the jumper to the green wire. It should shift to neutral. Then touch the jumper to both the green and blue wires at the same time. It should go into reverse. Remove jumper and it should go to forward. Remember, it has to be running in order to shift.

If it does all that, then at least you know the lower unit is OK. Likewise, if it does not do all that, you have problems in the lower unit.

The other way to test is with a voltmeter which will verify the condition of the shift switch in the remote control.
