I've still got the old Yanmar panel, functional but cracked. Just curious - what is the cost difference for the Mack Boring 278 Panel vs the Yanmar Panel? Oldport Marine in Newport has the Yanmar panel on the shelf so I know it is readily available. I would think the cost of replacing the sensors for the Mack Boring panel would negate any cost savings, if any.
Replacing sensors is no big deal. Oil pressure, water temp and tach sender just screw into the casting. I replaced the temp sending unit this past winter because I cracked the ceramic top unscrewing the electrical terminal. What you may find is the wire harness and boots that slip over the terminals are hard and no longer flexible.
