I have a 79 Wellcraft 180 which originally came with a Merc 140, but now the tach is getting flaky. I do not want to re-cut the cutout which is the ~2/12" size. Anyone know of replacements or the original part no?

Never mind. I did the right thing and went out and measure it. 3 1/4" cut out. So already bought one that fits.

Good. I don't think I've seen a 2.25" tach. Rare if there are any.
