I'm looking for a vintage/old tach for my '66 boat. I have an '83 evinrude 115hp but really have no idea what tachs I can use. Presently I have no tach. I saw "alternator" tachs...???
This is the Airguide tach I remember, or one very similar: http://www.ebay.com/itm/Airguide-Tac...VXDm-B&vxp=mtr . Apologies to the Ebay seller for borrowing the info, but there is some good Airguide info hyperlinked in the item description -- might find it useful.
(Your post got me off looking out of curiousity, and stumbled on the ebay listing. Think I was assuming you might be looking at or run across some vintage Airguides).
Yes, if you get an alternator tach. If you buy the Airguide, I suspect it might not work on your motor. It says for CD ignition in the ad. They used different CD ignition back in those days. But not totally sure.
I had a 1959 boat with fins. Had the Airguide tach in it. Was a 2-pole tach and was connected to the 1976 75 hp short shaft engine. Somehow it worked just fine. I bought it that way and never had to hook it up, so don't know what goes to the two poles. Obviously, one is the signal. I do not believe that it had an adjustment screw on the back of the tach to set the # of alternator poles, but that was years ago..
