V8J60 Tach options

[LCS]

Interesting thread, and I've seen that Mercruiser 62 (sweet!) but it was all greek (and geek) to me.

Is it saying that there is some Radio Shack fix (and that I was a sucker for the $100 Marks Adapter interface) I could use for the stock tach?

Hey, How did you mount this tach. Did you just press it into the opening?

Thanks,
Tim

Since this came back up to the top. I checked my tach against an aux one and mine read 1900 RPM when the aux one said 2000. It was closer at lower RPMs so I suspect that the error will increase as RPMs increase. I drive like a and rarely run up over 3K so that's plenty good for me! and boy was the price right.

thanks waggoneer!

Dremmeled out the stock hole until it just BARELY fit with pressure. Sucker ain't coming out.

BTW, I ended up cutting a hole in the back of the ProTach unit so that I could run separate grounds for the light and gauge itself. This allows the light to work correctly with the dimmer switch.
