When I'm at WOT the RPM will come up to around 4600 and it is not constant the needle is fluttering +- 300 RPM either side of 4600. It used to go right up to 5000 and stay there, sometimes slightly higher than 5000 but it would never flutter. Not noticing any significant change in sound or performance while this is happeneing, still seems to cruise along but I think it may be 1-2mph slower now. Its 90hp Mercury 0D076761. Guage NFG? or ?
