1993 Evinrude Model E40TEET will not stay at full speed

[Robert Edwards]

I have a 1993 Model E40TEET Evinrude outboard motor and it will not stay at full speed. It will go to full speed then quickly idle down to a slower speed.

Check to see if fuel primer bulb is sucking flat, try pumping bulb to see if keeps it running, may be starving for fuel.

It does not choke out. It will not stay at full speed. It will run but does not stay at full speed. It will reach full speed then quickly idle down to a lower speed. Still fast but not as fast as it can go.

Try bumping choke to see if helps or hurts it. Use a timing light to see if miss firing on any cylinder.
