Default 2001 1800 Sr burning excessive amounts of gear lube?

Does anybody have any suggestions on what my problem would be if I'm going through a lot of gear lube I do not see anything in the water or in the engine compartment or any leaks in the any of the fittings or anything it just seems to be burning through a lot of fluid all of a sudden? Thank you for any help!

Welcome aboard

If the gear lube is not in the bilge or leaking into the water it may be the upper seal and will leak into the drive shaft bellows. If you remove the drive and there is lube inside the bellows it's the upper seal. If no lube here drain the drive and perform a pressure test. Typically a leak is not dectable in the water because it mainly happens when the prop shaft is turning at high speed. Any sign of water in the lube if you remove the drain plug?
