787 Counterbalance Shaft Timing

[RMSeaDoo]

I know this has been addressed before but I have a rebuilt crankshaft from SBT and I’m not sure if the alignment mark is correct.

Based on this seadooforum thread the crank and counterbalance weights should be 180 and 0 degrees apart. (Never mind not enough posts to put a link)

The SBT crankshaft has a very faint mark shown in the picture below.

But when I align with this tick mark it looks as if my shafts are off by 90 degrees.

Is this the correct alignment or did SBT put the mark in the wrong place?

That doesn't look correct, the lobes should be 180 apart not 90 if I remember correctly. Are you sure that's the correct mark?

That’s the only mark on the crankshaft gear. I shined a light down between the gear and the bearing as well. Perfectly smooth except for that one mark. That’s why I was confused.

I would give them a call.
