Do you need to add gear lube during normal use? I have an '05 Alpha with gear lube monitor. When I bought the boat new the skeg was slightly bent from a parking mishap. The dealer said they would swap it with one from another boat. Don't know if they swapped the lower unit or the whole OD. I added lube twice in '05 (20hrs). This year I am ready to add for the 3rd time(21hrs) and it is down to the add mark. Hasn't been that low before. It has not been changed yet but I have checked twice for water. Looks good and no sign of leakage on the outside. Does this sound normal or should I have it pressure checked. I have little experience with ODs.
