Update on TinyTach
Well I went ahead and purchased a TinyTach diesel. The installation was a snap, my only concern was having a long enough cable to go from the transducer to the module. It is a coaxial cable, and so it would not be easy to correctly splice on an extension.
I purchased the unit with 12' cable (default is 8') and had no problems installing the transducer & running the cable neatly from the engine to the yanmar cockpit engine console panel. I mounted it just under it.
It works fine. I especially like the true engine hour meter which is built into this unit.

Could be the PO replaced the altenator with one off a gas engine that won't drive the tach.
If you look at the back of the alt. it should have a terminal marked tach.
Use a anolog volt meter and you should see the neddle bounce when the alt. is turned by just cranking, most digital meter won't read this pulse.

Never heard of it, but it sounds like it should work.
Most diesel tachs work in one of two ways: Counting pulses from the alternator, or counting pulses from the teeth on a gear ring on the camshaft. So, pulses is pulses and this one is counting pulses from the fuel injectors.
Should work just as well, clever idea.
You probably an get a used Yanmar gauge from Sailorman (Ft. Laud) or some of the other "used boat parts" places, with a little patience. Then it is just a question of whether you need a sender, or a connection to the alternator, and you probably can fix up the original system too.

desiel tach: Tiny-tach
The previous owner of my sailboat replaced the console Yanmar tach with a fuel gauge. He claims that the tach did not work(due to unknown reasons). The Yanmar replacement tach gauge goes for $180, but replacing it will not guarantee a working tach.
I have come across Tiny-Tach desiel (http://www.tinytach.com/tinytach/diesel.php). It works by sensing the high pressure fuel pulses. This tach sound like a great solution for my situation. Does anyone have experience with these tachs? Any recommendations?
