We have a 2004 Mercruiser 4.3L Bravo III with Thunderbolt V ignition. A couple of weeks ago we thought there was a shift cable problem, seemed like it did not want to go into gear, only happened in forward. Had it checked out and they couldn't find a problem, it was an off and on thing. Did tighten a couple of screws and thought that might help. Last week, we hit a submerged log, badly dinged the upper prop, had it fixed, seemed to be fine.
(this is background). Anyway this week after we are out about 30 minutes, all of a sudden the engine tries to stall, rpms go to zero, happened over and over, did not seem to be as bad the faster we went, but would still hesitate.
Made it home, called the marina, they thought it might be the rotor and distributor cap, husband changed that out, had a greenish powder in the cap.
Ran it back and forth in our cove for probably 20minutes, ran fine. Tried going out the next morning, started all over again, except this time it did die on us. Started right back up, but kept stalling out. Took it over to the marina (not far) and it ran fine. Any ideas? Sorry this is so long.
