I was checking around my engine to see why the tach wasn't working.
The tach drive (mechanical tach) cable runs to a gear set that seems
to drive off the front of the cam. The mechanism which goes into the
cam is broken off and is free to slide in and out. It looks like it
used to be a threaded pipe type arrangement but the threads are totally
stripped. Is this mechanical drive type arrangement common on inboard
engines (circa 1964/65)? I've seen mechanical tach drives on cars
which came off the distributor but not off the front of the cam.
Should I plan on converting to an electronic tach instead of trying to
fix this set-up? It's tough trying to figure out if the prop/engine is
functioning properly when you don't know what the engine is revving at.
Note: the engine is a Interceptor 165 HP based on a 260 cubic inch Ford
V-8.
Thanks, Wayne

| 799.1 | I'd replace with new electronic tach! | MR4DEC::DCADMUS | Fri Feb 22 1991 13:41 | 19 | |
It is probably going to be a whole lot cheaper/simpler to replace the
mechanical tach with a new electronic tach- the only problem is if you
are going to have an obvious cosmetric problem where the current tach
is mounted.
If the hole where the old tach went is too big, then you'll need to
sort this out. IF the parts are only a few $, then you may want to fix
the old tach, but if the threads are stripped in the end of the cam-
I'd plug 'er up and go with an electronic tach.
It's a matter of $, parts availability, work and cosmetics, and
condition of the existing cable and tach.
