502 harmonic balancer
Hi There,
i discovered an oil leak on my last run from the front left side of my engine, much more of a splash only whilst i was WOT.
since it was the other side of the oil cooler and seems to be splashing onto my fuel filter i figure it might have been from the crank oil seal.
after removing the damper to change the oil seal, i noticed that the part of the damper which fits into the oil seal seems a bit rough, so i guessed i should get a new one installed "since i believe was the reason of the oil seal to leak oil on high rpm"
now! my local dealer does not have a damper available, however i managed to get hold of a damper 3963532 number embossed on the back of it, seems to be the right one however has a different number to my previous one
# 10216339.
has anyone used same damper ( 3963532 ) on a 502 mercruiser before? should it be OK?
please help!

If I remember correctly the gen 6 and mark 4 have a slightly different external balance to them. If your balancing your crank either will work, If your just bolting it on use the correct one.
