1995 Yamaha 40 hp TLRT 2 cycle 3 cylinder outboard motor
The motor starts and idles fine but when the throttle, 703 remote throttle control, is pushed to full throttle the motor will not exceed 2,000 - 2,500 rpm. Sometimes the motor will tach. up and run @ 5,500 rpm but not often. I had an outboard motor mechanic, my neighbor, run the boat to trouble shoot for a possible cause but as my luck would have it the motor performed normally. Could the neutral switch be the problem?
I read that it could be an issue for some motors if the shift cable doesn't engage a neutral switch mounted on motor.
(I have ordered a new fuel pump, fuel lines and carburetor rebuild kit for the 3 carburetors.)
Any suggestions on possible cause or for steps for a process of elimination to resolve this?
Thanking you in advance,
