1990 25hp evinrude, tiller, pull start.
Rebuilt fuel pump, rebuilt water pump, cleaned and replaced needle vale on carb,had a new power pack installed. and was told the coils are ok.
Took it out today. It ran fine until after a long troll ;1/2 hour or so . I throttled up to go back up river,the motor got up to speed fine and then
started to run slower and slower until I was at 1/2 speed or less. Stopped for 15 30 minutes. Started the motor it ran fine.
Additional info
Rebuilt the carb,water pump, and fuel pump myself.
Had a shop replace the power pack. Their diagnoses
Today I replaced the tank. All hoses and bulb have been replaced.
While running pulled each plug wire. Made some difference but still ran.
Took it out to the closest impoundment to run it. Idles around for a few minutes ran great. Then wot and back to a little less than wot ran fine.
Idles again for 10 minutes then wot ran fine made a turn to go back to the landing. Hit wot motor started to sag twisted the tiller back a 1/8 to 1/4 and ran fine.Good stream of water out the pee tube.
Still at a loss
