Testing timing on 1992 Mariner 115 hp

[BJM]

Its finally time to check my timing. My Seloc manual says to checking the idle and WOT timing while cranking with the ignition leads grounded to the engine. What is a good way to ground all 4 cylinder leads?<br /><br />I guess the other choice is to check timing at true idle and at speed in the boat. The second one does not appeal to me at all.

Has anyone checked timing?

Have you done anything to the timing to cause it to change? I guess what I'm asking is, why is it finally time to check your timing?<br /><br />c/6<br />Hooty

It's just that I simply have never checked in the time that I have owned it. I bought it about 5 years ago and it was tuned at a marina at that time but never since. I just want to check it.
