Motorola RPM Gauge replacement
I have a 1978 Marine Trader with Dual Lehman 120 Diesel engines
On the main helm my Port RPM / HR Gauge died and I am looking to replace it without replacing the senders as otherwise I will need to replace the whole Port side set (Fly and Main)
Anyone here with idea / experience of which RPM gauge I can replace it ?
Pics below are the gauge in trouble
