Will do, I figured that was the case. Since I need a new solenoid sleeve and lead I will check out that discount.

Black wire from power pack ? Does it connect to the choke solenoid? Wire was bent leading me to think so.

 

[flyingscott]

Yes that is correct

 

[15fishperlure]

Thanks Scott. That completes the starboard side of the engine. Only the VRO starter and harness to put on and I should be ready to test the compression. There are still some wires that have me scratching my head but I'll post any questions of I need to.

OK these two wires come off the black box in front of the flywheel above the air intake. All of the wiring on the port side is plugs save for these plus one knife connection. As a note the vro oil has been plugged and I don't know if these are part of the alarm.
There are ground wires of course that connect to a shoulder bolt on the exhaust manifold.

 

[flyingscott]

Those are the 2 power wires for the tilt and trim I believe they should have purple stripes on them. Those wires should connect into the main harness somewhere by the red plug I believe.. The black box holds the T/N/t Relays you may need a wiring diagram.

 

[15fishperlure]

I will check when I get home for purple stripes. Both wires have eyelet connections and the wire is long. I thought maybe it passed back through the motor behind the carbs and screwed into that little bar. Will need to do more snooping and see what the manual has. I'm not good with diagrams of wiring

 

[15fishperlure]

There does seem to be a purple stripe on one wire. The connectors are eyelets so I don't think they connect to the harness. I can't see anywhere other than maybe to the starter solenoid. One picture showed a red wire connected to the vro

 

[15fishperlure]

Looking at the wiring diagram in The manual isn't helping as it doesn't show what the wires are connected to nor could seem to find the proper colors

 

[sutor623]

Maybe these will help some? This is an '84 75hp

 

[15fishperlure]

Yes as I thought on your 3rd picture starboard side you have a wire coming through that hole behind the carbs rear of choke. I think they must pull through. I found 2 posts that are backed out on the wiring strip (don't know proper term) back to the manual to see what i can find.

 

[15fishperlure]

Thank you so much by the way I see many things I have in the wrong spot

 

[sutor623]

Sure thing man, hope it helps. I sure miss that motor, she was a gem.

 

[oldboat1]

purple and white probably goes to the choke solenoid. Check the wiring diagrams and color coding in the Mastertech link in the "top secret file" up at the top of this forum.

Well all together. Testing the compression in the morning. The colour photos were far more help than the manual
Thanks everyone for help identifying parts and sending pictures.

 

[15fishperlure]

Tested with the muffs in the drive way last night. Water coming out the thermostat cover cause guy never tightened the bolts. Really hope that is separate area form main engine. Tightened down and no leaks. Major fuel leak somewhere in the carbs, wondering what he never tightened in that area.

 

[sutor623]

Where is the fuel coming from? Is it from a carb body?

 

[15fishperlure]

It looked like the body till I pulled off the air silencer. Turned out to be the gasket on the air cover was not aligned and was covering the return hole at the bottom. Really happy about that No more issue
Still have a dead temp alarm which needs to be looked at. The replacement sensor has a ground and the tan sending wire but on mine there is only the tan wire unless it is grounded inside. Would prefer to have a working overheat horn right.

 

[juno pierrat]

sorry haven't read all posts, but many(all) 80's motors are just one wire temp.sensors, with the key on and knife connection at sensor apart, ground wire from the wiring harness, the alarm should sound
