I have a 1995 Evinrude 112 on a 95 Wellcraft 119CC. Today I was anchored for a while after traveling about 10 miles at 3/4 throttle with no problems. When it was time to head back to port the engine wouldn't start in neutral. Just kept turning over but never started... So I gave it a little gas in neutral and it started but the RPMs were really high. I tried to throttle back into neutral and the throttle lever wouldn't go back that far... there was resistance... I pushed a little harder and it slipped past neutral into reverse, but the RPMs were really high again... so I was able to make it back to port but pretty much only have 10mph and faster, and full throttle reverse... nothing slower and no idle... Any ideas?
