I just purchased a 1997 Evinrude 115 which was working fine when I looked at it prior to the sale. Now, it starts and idles with no problem, but won't rev past 2800 rpm. Occasionally it will race as if in neutral. Plus it makes an unusal racket when in neutral. Does anyone have any ideas what could be wrong with this motor?
Not being able to listen to the motor or experience the erratic running, we would suggest that you have an authorized Evinrude dealer check the motor over for you. Once the problem or problems are discovered, you can contact us in the OWNERS ZONE section for explanations of what was found to be the cause.

OK, so I discovered from the technician that the fuel filter was clogged up. So he replaced it and the motor ran fine for a while. Now the same thing is happening. That is, the motor runs sporadically up to about 2500 rpm. Should the gas tank be cleaned out?

If the filter is plugged up again, then yes, get that tank cleaned out along with the fuel lines and fittings.
If it is an aluminum tank, have it inspected closely as it could be corroding away internally from phase-separated ethanol fuel.
