Sometimes just asking an intelligent AI platform can provide some valuable info .. not always 100% but pretty good what is OMC type D marine lubricant OMC Type D Marine Lubricant is a specific gear oil used in older outboard motors made by Outboard Marine Corporation (OMC), which included...

ok in retrospect dieelectric grease is more for moisture in connectors and clamps no so much like true HV silicone...to stop arcing in old TV flyback transformers give it a smell test burnt stuff usually smellls.. burnt :-) points looked real dirty ..........hopefully a good clean...

hard to say for me anyway maybe Racerone can comment .. any burn marks are not very good and may indicate arcing althoug the stator is an AC generator not HV as in the ignition coil. arcing may have taken place from a close by " hot spot" due to a " better" ground proximity than plug...

here is one comment from an intelligent source....subject to approval.. :-) flywheel On your 1969 Evinrude 55 HP (model 55973A) you do NOT have a steady “voltage feed” going to the points like on a simple automotive ignition. That system is a battery-powered CD ignition with breaker points...

5v heading back to the breaker point may in fact be normal voltage... That wire is there only to "sense" the ground furnished by the points. I have no info or voltages specs on the internal desing of that " amplifier box" and how it increases the voltage burst going to the main ignition...

wild guess again ( I admit not knowing your engine but yout mdl # shows it to operate with a break point) reading other sources indicates that if you simply tap a quick GRD on the wire from the breaker point the"amplifier" should fire the ignition coil and you should see spark. all the...

post exact mdl ans ser#... if the kill circuit is not the cause the " amplifier" is suspect according to Chat... this may.. help but if you have no tools to test ....shop time may be on the horizon. techs for 1969 engines are getting rare..and $$$$

lots of comments about these batteries on ETEC technology.. BRP recommends lead acid or AGM

Mat..??? would a stuck open thermostat cause an overheat ?

there are several much less expensive rec. reg on the maket that can do the same and simply need to be " fitted". check amazon this "mercury one" is $24 grounding is via mounting bolts. 6-15 amps charge cap...

is the head warped ? was it checked out with a straight edge ? it may need just a good cleaning with a sharp blade and wire brush.

if you do not wish to pull the cyl head from fear of damaged bolts have you considered some products like rid-lyme etc... maybe you can flush out some accumulated crud. see utubes. or work slow on the bolts ! check lower cyl head hose for clogs

to clean the innards of the water circulation cavities you could run some descaler product ... check Rid -Lyme etc... check utubes

oops :) brain fart

impeller !!!

sounds bad if it did rotate 360 at one point... Racerone may be right ! broken something...? may as well pull the cyl head check the walls for bad scrapes.

see maxrules diag. if it helps looks like kill is a normal open switch. should be easy to track down https://maxrules.com/mercwireindex.php

patience... my $50 turtle was locked solid ( which is why the seller did not argue about me buying an anchor !) I took off the cyl head. (gaskets are cheap anyway) soaked and soaked it took a week to free it up. in slow increments. used a 1 inch round peg and hammer to alternate...
