First off you all have been great with answering questions and helping with solutions.

You might remember just finding a split in my plug wires so we know its time for them to go and since being in that far coils of aren't a bad idea to change knowing that very well with age probably time to replace . I came across ignition coils made by "AutoKay", the price was great. Anyone here heard of this brand or used? The numbers of course match up for use. got points and condensers coming as well. Here in the Carolina's there is very little down time if any to be on the water.

I figure only question NOT asked are dumb ones.
 
They are Chinese made and I have had several customers use them with success, only use the OEM points as the aftermarkets are not that good.
 
Right, agreed. Aftermarket points often have a very thin layer of silver over the contact area. Why? Maybe they save a little money in manufacturing them. Silver is our best known conductor of electricity. A heavy silver layer makes the points more durable. Also the material used for the lever arm is whimpy, making alignment of contact points unreliable. I also question the quality of cam follower and pivot bushing. Points and magneto ignitions are very reliable when properly set up and maintained. I have NEVER EVER been stranded with these motors. BUT......electronic ignitions have died on me without warning many many times.....often creating hardship and destruction of time.
If upper crank seal is leaking oil, enough to get onto points, you should clean very well and maybe consider replacing that seal if it's gonna be your "everyday" motor.
 
A hint on installing plug wires... and the coils themselves to the armature plate...................

I don't know about the Chinese coils BUT all other coils thatI have installed... the pointed pin inside the coil that the plug wire attaches to... that pin has a spiral to it. So when inserting the coil wire, use a little WD40 on the wire insulation for easy insertion and twisting as you screw the wire onto that spiral as tightening a screw.

Also... notice the top edge of the aluminum that the metal portion of the coil seats upon. You'll see a tiny bevel there. The vertical metal portion of the coil must align with the inside edge of that bevel to configure the proper distance between the coil and the flywheel magnets.

Points... align the flywheel key with the fiber portion of the points... then set the points so that a .020 gauge will slide thru but a .022 will not.

Thank you all for this outstanding info to this newbee
 
Some points are hard gold/palladium/nickel, but don't think they are available for this application.
