Re: [OMC-Boats] oh happy day

ahh so you sound like you are having the same tach prob as me. Yeah,
i'm going by sound also - but i'd prefer not to. I put a new tach in
my last year, maybe it has some sort of calibration adjust screw in
the back. but then I have to know where to adjust it to anyway. If
it does, I may just get it to where it says about 900 at idle - close
enough to get by with for awhile.
