Ours has given up the ghost (gee it's only 37 years old J). Is a Hitachi WI 1-05 dual purpose for low oil pressure and high temp. 5 pin connector. 4 pins are used so not quite sure how the wiring would work if went the Yanmar 3GM engine = type B panel. 2 1/16"hole. Issue is locating one of these - with the caveat of a reasonable price. Did the Google search. Found one on flea bay but $75 seems like a lot when can get a single purpose piezo buzzer for about $15 and just need to change the wiring.
Any suggestions for sourcing or alternative strategy? John and Maryann Legacy III 1982 C&C 34 Noank, CT
