could andres distributor be off a notch so number one is not really the number one cyl? and thats why it reads runs correctly at 0 degrees on harmonic balancer?
has the motor been rebuilt or has the distributor been out of the engine that you know of ?
the simple and fast thing would be just to try the sensor on the next or previous spark plug wire on the distributor and see if its close to spot on. or go about determining tdc on the number one cyl and see where distributor is pointing.

My theory is his dist. Gear is installed 180 degrees off on his distributor.. being a 13 gear tooth that gives about half of almost 30 degrees. Or just under 15. Which could describe close to his 10 degrees off of correct advance.

A full tooth is 30 degrees which doesnt sound right.

Hi There,
I was trying to check the timing on my 2005 X2 with the Indmar MCX 5.7 HO Vortec engine.
I can see a single mark\groove on the main pulley and I think it needs to match up with a notch next to it.
I don't see any degree marks on the pulley or near the notch.
I connected the timing light to Cylinder 1 - the first cylinder on the RHS as I face the stern of the boat.
I put the engine in 'Base Timing Mode' using Diacom
I don't see the timing mark on the pulley at all when I trigger the light (I do see it if I connect the light to cylinder 8 but that is incorrect I think)
Am I connected to the correct spark plug lead?
Should there be degree marks on the pulley or beside it?
Am I blind!!!?
Why don't I see the timing line on the pulley?
Can you set the timing using Diacom without a timing light?

Thanks in advance!!
Justin

The groove and pointer donít line up unless the timing is at 10 degrees BTDC.

Thanks Jim
I thought that was the case.
I would have thought though that Iíd see the timing mark on the pulley close to the groove even if not exactly on it with the strobe light.
Engine sounds ok so I donít think the timing is way off.
