I have a 115 Yamaha (1990) I ran it every week til after the 4th of july.. Had it sit up since waxing the bottom and repairing the trailer..
It was cranking up fine, but did notice that it would start bogging down.
If I hit wide open throttle it would hesitate 1 sec. then jump and go. Well today I went and checked the fuel filter, it had a few specs of trash, nothing major at all. It got to the point where it would not run..took a long time to crank ... Finally got it to crank and idle (1000 Rpm's) I hit the throttle wide open and it fell on its face..I hit the electric choke and it took off wide open then slowed down and dying..
I pulled the carbs and fuel pump. Cleaned the carbs but did not see any blockage.. as for the fuel pump, it looks good.
i could use some pointers ..
Where is the low speed jets spray from? I have some pictures attached.
I replaced the plugs after doing that i noticed it had a tiny spray of fuel from a pin hole in the bottom carb line when I primed the bulb..I fixed it and no change..
I'm going to get a new fuel pump in the morning. The boat is still in the water here at home..Bad part is I'm goin to Destin tomorrow evening and I think I might be taking the blow up pool raft if I dont get it up and goin..ugg
Anyway all help is much appreciated..I'm mechanically inclined, so let Me have it!!
