Attn: Yamaha Mechs. (Water temp Gauge) install

[77SceptreOB]

Well to answer my own question:

Yes, I have learned those are the "bosses" for either a Water Temp. Gauge or a Water Pressure Gauge. If you order from Teleflex, you will need a special adaptor to fit the Yamaha boss. The Yamaha motor uses a M14 metric sized port. The standard temp sender unit provided by Teleflex in the Water Temp. Gauge kit will not fit the Yamaha port. The special adaptor is Teleflex P/N 61886P.

FWIW, the Teleflex Water temp. gauge is a lot more detailed and much easier to read than the OEM Yamaha gauge.
