Tach for 75HP Chrysler.

[Tnstratofam]

I want to add a tach to my 75hp Chrysler outboard. Just looking for opinions on a decent brand. I bought an old one from a local marina that I was told would work, but it doesn't. I've looked at the Faria brand, but I'm not sure what would be good. Also would I be better off to by the tach in a set with water pressure/temp and so on? Ive already got a good spedo on her.

i got a tach from harbour freight for 20 bucks and it works fine for two years now on my 70 hp chrysler outboard.

You can still pick up the originals if you look hard enough, otherwise I bought an electronic one which I still had to calibrate with my handheld tacho.

I'm guessing the tach you need is a 12 pole?
The motor, what's the year?

 

[Frank Acampora]

The tach used depends upon the year: If the engine is pre-1978, with a distributor, then a 12 pole tach will work. If it post 1978 with no distributor, then it needs a 20 pole tach. These tachs are becoming more difficult to find. You can also use a "Tiny Tach." on either model engine.

I think the engine is an 82. Or at least that's what I've been told here on the forum.

Here are a few pics.





Thanks for the replies by the way. I know the forum is jacked up right now.. Makes it a pain to post..

No Title

It is definately post 1978, as that is when the lower unit changed to a one piece, the only Chrysler tacho's I have seen have a setting for 1,2,3 and 4 cylinder, I have had 3 of them, but ended up with an electronic one from China which I calibrated with my hand held.
Hey you can still get the prop flare and prop cones for those old Chryslers, I still have a flare laying around here somewhere.
