Cas42,
Thanks for the info on the maintenance of the panther unit. I was able to locate the dip stick just inside the transom, appears to be a bolt with an extended hex head? Have not checked yet, the access is very limited to the dip stick. As for the zerk fitting, I was not able to locate this. I viewed the exploded diagrams of this unit on ADM Boat Works website, found the callout in the parts list but unable to locate in the diagram.
