I'm looking for any direction as I start to diagnose this, i've read tons of great posts and plan to follow the direction. I just bought a boat with a 1974 merc 1150 (serial # 3945671) on it. I mistakenly didn't test it because I trusted the seller. He claimed it ran like new. Well it did for about 10 minutes. I was smooth and quite and idled great. After a bit At near WOT the motor completely died in an instant. It easily restarted and ran well for another few minutes then cut out instantly again. After getting it home I came to find that I have no spark in all 6 cylinders. All cylinders had 125-130 psi compression (happy to see that).
Now I'm chasing the no spark. I started taking things off to test the switch box and came across something weird (i think?). The main wire that heads from the distributor to the coil, or into the red thing in front of the coil was very loose inside. (i'm new to these older motors) It pulled out very easily, being a cylinder type pace of metal I'm assuming it's supposed to clip onto something, the way a plug wire grabs a spark plug. Should there be a post in the red thing? Any insight of guidance would be greatly appreciated. I can't get a picture to load so it's my profile picture. Thanks so much, I'm very excited to get back on the water.
