A couple of questions........

[Rico]

I’m a recent new owner of a 2005 3200 open w/ Cummins 
The boat has trolling valves installed, there are 2 valves in a small pocket on starboard side next to helm seat. Does anyone know how these are adjusted ? I don’t want to start turning them in/out to see ...........

Also amongst my toggle switches there are 2 that I’m wondering about;
1. Low idle toggle
2. RPM +/- toggle
The RPM on has me confused as to why? It will actually reduce potential power down to a crawl with throttles wide open......

Thanks,
Ric
