Can someone tell me the timing marks on a 1986 OMC 5.7? I can see the pointers fine, but there is no markings of what degree is what. I think there are 5 or 6 points on it.

Cuda...

The timing marks that mate up with those on you block are actually scribed into your harmonic balancer... take a timing light and shine it on the timing marks... you should see scribe marks on your harmonic balancer... if not, take some fine grit sandpaper to your harmonic balancer... they are there....

This one only has the one timing mark on the balancer, and a peice of metal on the block with several points on it. I will post a picture tomorrow of it.

Hi I know this will raise some eye brows, but try this and I know you will like it. Put the timing light pick up on the COIL wire instead of #1 Now you can see things you never saw before, everything stands still with no blinking crap. When done done check it on #1 and you will see it is Exact. I've been doing it for to many years to remember.
