Re: 2000 175hp Evinrude ficht motor wont idle

there are a number of things that could cause a fast idle at startup. Besides sticking throttle linkage or a throttle position sensor, a serious condition could be a fuel leak into the intake manifold or crankcase such as a diaphragm pinhole in the lift pump or a flooding VST vent.

 

Because it could become serious and possibly a dangerous situation, we recommend that you contact a dealer for having the motor checked over before using it again.

Throttle linkage moves correctly with no hangups.
Tps ohms checked shows 1.1-6.8
Tps moves freely
Should I replace or rebuild the lift pump to narrow it down?
How would I check for a flooding vst?

The factory service manual outlines pump repair or replacement depending on the type. The VST is a replacement item only, not a serviceable part from Evinrude.

 

You will need to contact a trained technican or obtain the required equipment and service literature and learn the system and procedures. If so, please read the disclaimer at the bottom of this post.

I have already replaced the vst
I will look into rebuilding or replacing the lift pump because I have suspected it from the beginning.
I will obtain and learn the correct procedures. I have read the disclaimer. Thank you
