RPM indicator

[Francisco]

Juan, Last week I had the sending unit replaced on the front engine, got a replacement from Comodore aerospace cost $ 250
Call Don he may have more.

PS you can avoid having to send off your gauge in the future just have your mechanic check the gauge by conecting the rear sending unit to the front engine gauge, and if it works then you know it is not the gauge. That is how we found the problem in my 336

Buena suerte (good Luck)

Saludos,

Francisco
