1968-1972

HI everyone.

yesterday i bought a Johnson 50hp hydro electric drive outboard engine.

im trying to hook/wire everything to the boat. unfortunatly i cant seem to find the wiring diagram explain for the ingnition swith. ( wich wire do what ? )

since im new to this ( first boat )

i dont have a key switch for the boat so i've went with a push to start switch with 3 toggle switch with it .

any idea where i can start !??

Just be aware that 12 volts from battery is not used to make spark at the plugs.

What year model is it? With that info, we can probably supply that information. Or what color are the wires that you're working with? I'm guessing there's a black wire and a red wire, what else do you have. Why 3 toggle switches?

 

[brodmann]

Here's what I see for other evinrude motors around that same year.
Purple/white - Choke (if electric)
Purple/red - Battery +
Black - kill switch
Yellow/red - starter solenoid
Black/yellow - battery -

A 50 hydro-electric can only be a 71 or 72 model !-----I would ignore the info in post #4.----Applying 12 volts to a black / yellow wire might result in expensive smoke !

I couldnt find the exact years i went with what ive found on the internet by typing hydro electric drive

There is no plate on the engine what so ever and has been repainted all black.

Im guessing jn between 68-72

For the kill switch its what ive tought the black wire should be the kill switch.

Ill take some picture to post by around 18h00 east time.

Showing what kind of swiftch im using and cables im workin on

???----It can only be a 71 or 72 model !!!-----Post a picture if paint is original on the engine block.-----I can identify the year in 2 seconds by paint color.

i couldnt take a picture yet but the engine color is like sahara beige

Kinda look like this one actually.

im having issues trying to use the forward reverse neutral switch.
i might be dumb cause any wire i hook to it seem to do nothing at all.

can't find how to wire this thing up.

engine is running tho. but its like always engaged forward ?

 

[brodmann]

Racerone - my post (#4) clearly shows
Purple/red - battery +
Black/yellow - battery -
Those are (+) and (-) for positive and negative.
I'm trying to help the guy with information I found online. Can we just help folks that need help instead of criticizing each other?
You can be incredibly helpful at times, and I appreciate you being here. I'm sure you have a tremendous amounts of knowledge and experience, but that doesn't have to make the rest of us idiots, does it?

 

[racerone]

We have a novice boat owner here !---Possibly a wiring mess on his hands.-----I clearly stated to be careful with wiring on this 1972 motor to avoid expensive mistakes.-----Helped a novice boater a few years ago.----After stating that red goes to positive and black goes to negative I saw smoke.----Just 10 seconds after my caution he hooked the battery up backwards.----That is the way I see it !!!

 

[brodmann]

Fair enough. I understand.

 

[skeletikx]

sorry guys for the delay !

iv'e been really busy out there.

so right now my problem is only my neutral and reverse.
engine is running so for that part its all right ive been able to fir a cable for the throttle.
the only thing is when i start the engine its always in forward motion i cant put it to neutral or reverse.

i cant seem to find any electrical diagram showing how to wire this thing up.

i was wandering if i can create a new one with like 3 push or toggle switch ?

Check to see of power is going to the Shift Wires under the Cowl when the Control is in Neutral or Reverse. If Power is, then you will be dropping the Gearcase for Inspection. If not, then the problem is in the Wiring to the Control, the switch in the Control. Power must be getting to the Control Box as the Engine will crank and run.
Several people have Jury Rigged a Toggle Switch system to control the Shift. It isn't too hard. Power to the Neutral Solenoid for Neutral, and Power to both the Neutral and Reverse Solenoids for Reverse.

Here is couple picture i just took.

the last one is my switch for neutral and reverse.

black = blue
white = green

Im trying to find the "purple" wire that i need for this picture

im terribly lost right now

 

[racerone]

This motor suffered from severe overheat.----Do a compression test.----Post the actual numbers here.

 

[jimmbo]

It certainly got hot

 

[racerone]

Paint color is for 72 models,

this is for a bigger engine but the basic shifting should be very similar

power is sent to the shifting coils via the top right shift selector which applies 12v to the appropriate wires feeding the shifting coils blue or green

power comes the the A switch terminal on purple and is feed has deisred For R... each shifter coil has it's own ground and work independently . no power to either is neutral

[racerone]

No power to either one is FORWARD on these.

thanks for the update. yes the default is FWRD so one does not get stuck !!
