Need some help on how the rings are installed? The merc manual I have and the sheet that came with the rings seem to be different. Oil ring not an issue, middle ring not an issue, little dot goes towards the top of piston. However the top ring has no dot and the hasting sheet that came with the rings shows the grove to be in and facing up, where as the manual I have shows the grove on the ring to be facing out and up. That can't be cause the grove can only be installed up or down on the inside of the piston. I hope this is making sence. Rings are hasting moly part # 2M598-std.
