Have a sailboat with PerkinsSabreDieselEngine.
Seems that the Tachometer is still functional but the hour meter within has died. Any recommendations for a stand alone hour meter I should install ?
Have heard that Hobbs made great products years ago, what about now ?
Used similar for both engine and bilge pump. Mounted at nav station, don't worry about salt water exposure (hopefully). Very happy with results and makes it easy to annotate the log.
