Ok, after cleaning every electrical connection, and I mean every one, I'm happy to report the alternator is putting out a little over 15 Vdc and the battery is getting about 13.3 Vdc. I brought the engine up to temp and the readings stayed steady. I'll do a longer test before going back on the...

What is this black magic of which you speak? This "one wire marine type"? I've looked an so far everything is about going to a one wire alternator. Would this be a internally regulated alternator?

Well, that would be the only remaining item. Transom mounted unit.

Every connection point at this time has been spit polished to a keen shine. When in question, wires have been replaced with new wire, slightly oversized application appropriate wire. Once I get this back in and I am still getting an overcharging from the alternator, I will pull out what hair...

The picture doesn't show it very well but I did clean up the contact areas in the holder so the fuse has a good clean surface.

All the wire I added was tinned 14 AWG. Ground wire from the harness attaches to the aluminum bus strip.

I pulled the console panel out and this is what greeted me. Some of the wires was smaller and not tinned. They were replaced with 14 AWG tinned wire. Marine grade heat shrink applied to connectors and mechanical connections have been varnished. I cleaned up all contacts and in some instances...

OK, the red and wire goes to battery. The green wire (field) goes to the voltage regulator mounted on the transom. That leaves the yellow/black wire to be the sense wire. All the connections are polished to near mirror finish and then coated with electrical varnish. It sounds as if the...

Not sure I'm following. Bad Sense leg on the ALT?

Battery online, ignition switch in Run: Volt meter is zero or drops just slightly below zero. Trim motor does not spike volt meter.

I fired it up last night and monitored the voltage output at the alternator, at the battery and starter. On cold start up the alternator output was 16.4 VDC. After about five minutes it dropped to 15.2 VDC at alternator, battery and starter. Meanwhile, the volt meter in the dash dropped to...

Well, I thought I had this dialed in. Took it out today and volt meter was showing in the positive but over the course of an hour or so under way, mix of WOT and low speed cruising, it dropped down to zero. When I hit the trim switch the volt meter would jump up to where it was on start up...

There isn't a plate. The boat is a 1969 Starcraft Starchief. The serial number on the outdrive is 2528633, which puts it in the era and indicates the motor was a 120 originally. My suspicion is it is not the original motor.

I have not had any success finding anything about this engine by its serial number. There isn't a tag anywhere on the back of the motor by the starter. All there is, is the number stamped in the block below cylinders 2 & 3 on the right side of the engine. 1M10082RQ

Now that I've ironed out my latest issue with electrical, thanks y'all!, I'm looking to reverting my carburation back to the original configuration. The current carb has the larger base 3 3/4" x 2". The original carb has the smaller base of 3" x 1 7/8" and much smaller bore of 1.47" versus...
