Where To Buy Small RPM Gauge

[jackreno]

Where can I find a small RPM gauge, 2 inch size, have checked on the internet and boat stores and all theirs are the 3 inch size, my small rib boat has a small helm and no room to install a 3 inch gauge, or can I install the gauge outside the helm in a enclosed gauge case ?

Also what about a electronic RPM gauge, do they exist.

Do a Google search for 2" rpm gauges
Yes there are digital ones out there that would work for what you have explained
If there is a good marine electronics store near you I would bet they have the parts to fit your needs
