One nice thing about this E-NATION website is that you do not have to repeatedly ask the same question here.
We have replied to your query already in one of your other identical posts.

I guess I did not fully understand your initial questions, forgive me.
See your dealer to order the complete factory service manual as it contains the technical and repair information.
As a former pilot and boat racer I understand the need to know the condition and operation of the engine at all times. Be aware that the engine computer, EMM, controls the operation of the engine and that some parameters are not adjustable or able to be modified - engine idle speed is one such item.
If you have additional questions in the future, please post them one time in the OWNER ZONE forum. We welcome you as a member of the Evinrude family and look forward to reading more about your unique approach to boating. I am sure that you will empower others in your situation. Thank you for joining us here at E-NATION.
