There are a couple of dozen reasons the check engine light is doing that, so the best next move is to find a way to read the codes that are being thrown by the computer. It may be minor, and probably is, but there are major problems that will cause the light to come on as well. I would take it a trusted marina with the tools. I am including a link to a good discussion I found about this ... Good Luck Evinrude System Check Check Engine Light The Hull Truth Boating and...

the idle circuit in the carby still has a blockage that is preventing it from allowing the fuel through
compression is good
possible that the ignition timing is not correct
at this point I would suggest that the carby be overhauled by a Evinrude service shop as rubber from hoses , fuel pump breaks down and fine particles get into jets and passages and block up the holes

Never heard of a 490. Decades ago, Evinrude made a 4 cylinder (V4) 90 hp. It would be helpful to know the approximate year of the engine!

Hi, it would probably need a 17 inch pitch and then water test it and make sure its full throttle revs are between 5200 and 5500. regards Phil.

You can get rpm data by searching your browser using "90hp Evinrude Specs" or "1982 90hp Evinrude idle specs". Changing the jets usually costs you performance on one end or the other. If you have needle rods, a narrower one will have the same effect as a bigger opening in a jet. But you have rpm limits that you should not exceed. Changing the prop can give you more power over the sacrifice of top end speed.
