Glad you're making progress. I have Glendenning synchronizer and cruise system but, I don't know anything about the switch below the wheel. Also, never tried my RPM +/- other then when the cruise is on. I wouldn't think it should do anything unless the cruise switch was in the on position. One more thing, I have never heard anything good about trolling valves. One of my fellow Tiara boating buddies lost a trans on a 35 Open do to trolling valve malfunction.
