55 H Tach

[jon66w]

I am building up replica of my old DSR with 55 H power. I am looking for a boat mounted tach that will work with old 4 cylinder, 2 stroke magneto/points motor. Tiny Tach and Digitron said their products won't work as this ignition system is too electrically noisy for their inductive pickup.Does anyone know if the old Aeromarine tachs that were hard wired to the mag, I believe, are still available or any other solution to a dash mounted fairly compact tach???
