timing

[brodie123]

Hi All;

Can anyone help me identify the timing marks? I have not been able to find anything that matches what I have.

Mercruiser 165 inline 6 4.1L i/O

I really need to know what the marks are in order to get proper timing. I outlined the marks so they are easy to see.



thx!

Cant see em all that well. Deepest notch is prolly 0 degrees. The round tube is for a magnetic timing pickup. Diagnostic machines (big boxes with screens that you USED to see in every shop) used to use them. Quick way to set timing, see stack/roster patterns and tune engines.
