I have a 2000 Merc 150 XR6. She ran consistently at 5400 - 5500 RPMs @ 64mph (GPS'd). Two months ago had a eletrical fire located in front at trolling motor plug. Replaced all front console parts including tm with identicial parts. Problem is no she will not turn more than 5000 RPMs @ 57.5mph (GPS'd). I have checked throttle linkage, tilt/trim switch, and everything I can think of. Motor height has not been changed, same prop; same everything except loss of RPMs and top end speed. Motor starts easily and idles like a dream. Hole shot is perfect as always. Just really stumped at loss of RPMs. Any help or ideas would be greatly appreciated.

Tight Lines :)
