- 2 Mercruiser 4.3l V-6 engines
I bought the boat this year, and have had no issues, except until the last trip. 1988 Sea Ray Sundancer, twin 4.3L Mercruiser 6 cylinder engines with thunderbolt ignition. The last trip, the port engine was hard to start, but finally caught, and we got underway. It started to overheat a little, but caught it and lowered the idle to get the temp right. Later found out that it was a bad water pump, and has been replaced. The next morning, the engine started, but cut out at low idle, and will not restart. I have verified that there is spark at the distributor and on eah cable, using a timing gun. Rebuilt the carb, to make sure it was not a fuel air mix problem. replaced the spark plugs. Still will not start. It sounds like it wants to start, but won't.
Also, there is a buzzing noise coming from the bottom of the engine with the key turned on. There has never been a buzzing noise there before, and no buzzing noise from the other engine, which starts with no issues. It sounds like it is coming from the front starboard side of the bottom of the engine.
I have a video of me trying to start it, and will post it once I get it uploaded to the computer.
Any ideas?
