Steve,
Rich gave you the answer for revving up the engine from your throttle
control, if you're talking about your idle speed when your throttle is all
the way back then you'd adjust your idle speed via a screw that is by the
linkage, by the carburetor.

I bought this boat with Force 120 outboard with maybe called Commander
3000 shifter. Could someone tell me how to raise engine rpm in
neutral ?
