F225 Yamaha issues

[Krjohns16]

OK...here's the latest...
My mechanic that was helping me had an ISC in his shop that he gave me (Saved me about $400 bucks) When I compared the two, the pindle was fine but the part that holds the pindle was protruding out of the housing about 1/8 to 1/4 of an inch. The replacement was not like that. SO...installed the replacement and all is well. I now know what an ISC sounds like when the engine stops. Thank you all for the advice for this novice, reluctant, boat owner (wife wanted it).

Any idea if this solves your dying in idle issue?

I don't know how it works ISC
I switched on and the ISC was very hot and my diagnosis was 69%.(previously shown 30%)
I've tried a new replacement Still hot as before (switch off, there is a click for 2-3 seconds)
Question: Does the ISC work like this?
