I have twin motors (BBC's) and would like to use one tach (with an indicators for each motor) for both . You ever see such a thing?

Re: Dual Tach

They make a single gauge to read two engine RPM's, but it's usually designed for aircraft. It would look out of place on a boat as it is generally a round gauge with a square frame and the corners cut off. It's probably also expensive as heck.

An easier way to go would be to install an engine syncronizer for the twin engines. Then you can run one throttle, one tach, and control both engine speeds identically.

Re: Dual Tach

Ya I saw the airplane things but they were for turbo props and such. Not sure they would work on a Chevy V8. The engine sync thing is nice but expensive.
I would love to use some thing like this but I'm thinking without some sort of box to go with it it wouldn't work.
