Not to highjack the thread, but I too have an old 120 and do not trust the 50-year old analog Craftsman dwell meter I have left over from back in the day. I do have a Fluke 101 multimeter bought recently (6 years ago), and understand that I can measure % duty cycle, and convert that to dwell...
No pos or neg sides to the switch. You can wire it in either way. It works by breaking the connection from the ignition switch to the starter solenoid.
In your situation, I would think about carefully cutting off the top of the tube with a mini tubing cutter, the kind with a rolling cutter wheel like this.
You can get one for less than $5 at JEGS. You could also use snips or a hack saw, but it would not be pretty.
Cut the tube off below the...
The way I understand it, having worked on exactly one outdrive, but after studying it thoroughly and with a lot of unrelated mechanical background, is that once the shims are set the first time at the factory the spacings don't change over time. You have to reshim if new parts like bearings or...
"You seem to want a QUICK FIX."
A quick fix would be to buy an SEI and be done with it. Or dropping it off at a shop and picking it up when it is done. Fixing it himself will be a slow, interesting, fix. He is probing whether that is feasible.
An alternative strategy for going forward, so to speak, would be to put it back together with a seal kit after welding, and running it until it blows up. Might run forever behind a low-power 120 and with typical low annual running hours for a recreational boat. Only recommended in...
You sound like you are holding to the possibility that it is the belt. If you feel lucky and have time, get a new belt and find out. Afterwards, you'll have a spare!
Hi, Tyler. Good luck with your project. I've been working on something similar. A 70's era runabout with a Merc 120. I bought it a year ago, full of snow and pine cones. Had not been run for a few years. The boat was free, essentially, since the trailer was worth what I paid for the boat...
13.21 would be in the normal range. It can vary anywhere from 13.0 to 14.5 and be fine. Your alternator is charging, but the front bearing has likely gone bad.
There may be an automotive electrical shop in your area, look for one that does Generators, Starters, Alternators. Getting them to...
