I have the same options on my 38' Open. The "low Idle Rocker" will reduce your idle speed by 50 RPMs when your in canals or low speed areas running at idle. Not recommended that you run the engines with the low idle switch on for long periods. The other switch is your cruise control. You have cruise control 1 & 2. You can set one for low speed cruise and/or one for higher speeds or anything in between. The +/- adjust those speeds. See your manual, it explains it pretty well. Good Luck Tom

I just re-read your post and I have a question about what you describe as trolling valves. Are they recessed in a small plastic box next to the helm seat? Are there 2 small knobs that you can turn and accompanied by one or maybe two rocker switches? If this what I think it is these are your back-up throttles. Your throttles are fly by wire and these back ups are there in the event of the throttles failing.
