[C320-list] Tachometer

[Barry Fahrer]

There was a thread a while back about using a hobby Tachometer to check the 
on board instrument.  Does anyone have the make and model of that device.
I believe my instrument panel may be off as I am only able to rev up to 2800 
RPM in Neutral
and 2450 or so in gear with a 3 blade flex o fold prop.  The boat seems to 
make hull speed and I get no black smoke.  I have just over 700 hours on the 
1994 Perkins.
Thanks for the help.
