Digital Gauge Application

Will the following gauge part numbers work on Yamaha outboard and if so what model year applications?

Tach: 6YE-83500-00-00

Speedo: 6Y5-83500-M0-00

They are coming off a 5.7 stern drive unit.

I may have answered my own question.

I think that these may only work on outdrive units.

Please correct me if I'm wrong.

No I don't think they will, might be able to use speedo but not tach.
