C10 gauge

[FlyBy69]

Just brought home a new boat with Suzuki 200 and a C10.. I can't program the gauge because the enter key does not work. Can't break the engine in without a tach. Any ideas?

Warranty will apply to a new C-10. Take it back if the key is faulty.

No other realistic option.

Thanks, that's what I thought.
