Jane: If you're experiencing an overheat when you exceed 2800 RPM, it is very likely that your exhaust elbow is coking up and in need of cleaning. The exhaust backpressure will cause the o/heat. You should be able to achieve 3400 RPM easily without associated difficulties. See the archives for a wealth of info on exhaust elbows and overheats.Cheers; Bob Gillan, S/V Far Bugle
