Ok looking for some help. I got a 82 25hr Envinrude long shaft outboard I picked up last year. Had it looked over at the marina, had the lower unit pressure checked, passed with flying colors. The tech said the thing looked and ran great for its year and didnt' need anything else. Had him check it cuz it blew out some oil when I first ran it. Ran great all season, then started konking out on me. I'm about to pull it out of the basement. What it was doin is I'd give her a good pull, she'd start right up, rev up and then fade out withing 10-15 seconds, choke or no choke, throttle or none. I'm really hoping its pluggs so I can get it in the water, but...............I'm thinking I might be looking at a fuel delivery problem or dirty carbs.
