Hello, I have a 1981 Silverton 31c with Chrysler 318's. We boat out of Chester CT, and last week we went to Block Island with a bunch of other boaters from our club. The boat has run great this year. On our way out, literally 5 minutes from the slip, the starboard motor started to bog down it went from about 3000 to about 2100 or so for a few seconds and then came back. It happened again about 2 minutes later. It didn't happen again all the way to Block Island (3 hours or so). While I was there, I checked my starboard anti-siphon valve, which had been clogged a few years ago. the valve was clear of debris. On the way home, as we idled away from our raft up, about 300 yards away, the starboard engine just stalled. It restarted fine, and it ran fine for about the next hour. On the final 2 hours of the ride home, it bogged down many times. I had to run at a slower speed in order to minimize it.
Looking at posts on similar issues and talking to some people at the club, they seemed to think it might be electrical. In my research, it seems an ignition coil that's failing can behave like that.
I went down a couple days later and swapped the coil. the old one was leaking oil, not profusely, but leaking. I won't have a chance to test it until next weekend, and since its pretty intermittent, it may not happen at all.
Has anyone had a similar experience with a coil on one of these motors?
