Mate has a Honda 90 1999 model. When out fishing the motor performs well for 3-5 hrs but then an alarm sounds and the motor goes into limp mode. It cuts a cylinder to protect the motor and can take up to 40 minutes before motoring can begin again. More times than not it re-over heats within ten minutes.
Any ideas as the mechanics are scrathing there heads and at $90.00 ph it's a worry.
