Mercruiser 3.0 in a 2001 Rinker 180.
Starts fine hot or cold. Idles fine. No issues there.
Wide open throttle runs fine.
However at partial throttle, it hunts. Especially, in the range of let's say 2750 rpm or so down to above idle, it acts like something isn't quite right. With a steady throttle, it clearly is hunting or surging. Not sure what to call it. But it it acts similar to a motorcycle that is running a little lean.
When taking off, just opening the throttle there is also a bit of a dead spot. Almost like you would get if an accelerator pump isnt firing.
My questions are:
1) Is this normal?
2) Do you have any guesses what would be causing it? Am I due for a carb rebuild? Or does it sound more like an issue w/ a Vacuum leak, distributor issue, clogged fuel filter, etc?
Thanks!
