I have a 01 mercury 125 2+2. It runs and idles great. But after about 20 minutes of cruising it will start to bog down if you go over 5000 rpm. If you keep it right around 4800 it runs fine for the most part. Might hiccup once or twice. It’s hard to test because you have to be going 35+ mph to get it to act up. Had a guy squeeze the primer and it didn’t seem to help. Where should I start looking
