Here you go: This is a short thread on hooking it up and making a diesel tach
work on an Atomic 4. The eBay link still works.

I have a Chinese knockoff of that tack I got for $32 on Fleabay and so far, so
good.

Well, I pulled Touche's engine panel today and lo and behold, the label on the
tach says Datcon 71725-00. So don't pay $350 for the Westerbeke part when you
can order the same part for $150,

Well, gosh darn. Touche's engine hour meter died (or went to sleep). Engine
is Universal 25XPB. Boat is in yard 4 hours away so I'm just probing around
the web for options.
First, it may be repairable. Might just be a poor connection. I probably
won't tackle it until I get the boat back to its home slip in Louisiana in a
couple weeks. An hour meter isn't that critical. However, on the chance that
it isn't repairable, I have two options.
First, install a stand alone waterproof hour meter. Cost $20-40 depending on
selection and another hole in the bulkhead.
Second, replace the tachometer/hour meter. Did that once already. Here's
where it gets interesting. It's Westerbeke part 011917. Typical online price
is about $340 US.

So I Googled "tachometer/hour meter" and probed around. Guess what? A Datcon
71725-00 tach/hour meter for about 1/3 of Westerbeke's price. Looks identical.
Spec says data source is alternator which I believe the 25XPB is. Here's the
tach:

Very interesting. Could this be the same tach? 3 3/8" hole. Next time I'm on
the boat, I'll verify the diameter and alternator data sensor. If I can't
repair it, I'll replace it with the Datcon. Anybody know why I shouldn't?
