I have a 4.3L Merc in a 2003 Bayliner. My engine is NOT fuel injected.
Here is my issue: Last year the tach quit working (i only mention this because I have read in other threads that the tach could point to an issue). The boat, which ran fine the year before, was running REALLY rough. You could smell gas. I took it to a marina and they replaced the distributor and cap. It seemed to run okay after that (though the tach still does not work).
This year the boat is running rough, but I have not smelled gas. It also seems to rev higher on its own sometimes- so I can be cruising along at 10mph and it will all of sudden rev up to maybe 15mph for 30 seconds or so, then back down. I cannot get anywhere near my usual top speed of 42Mph- limited to about 30mph.
Any suggestions?
