1999 90 hp ficht loss of top end

From every thing I have read it looks like my throttle position sensor is bad. Ohm check between the gray and green wires shows an open circuit at about 1/4 throttle then picks back up. The guage did not flash any codes with TPS hooked up, however when I removed it and put it at WOT it flashes a 14,81,12,and 26. Engine seems to run fine below 2500rpm then the check engine light comes on and it wont run over 3500. If i restart and throttle up quickly the check engine light doesnt come on but it still wont run over 3500 rpm. Any help would be appreciated greatly!

You should take your boat to an authorized Johnson/Evinrude dealer and have them put the computer on it.
