Hey Guys,
I put the ol' Sea Ray on the muffs this afternoon to warm her up before hitting the water after a long week of work. Everything goes without a hitch until I shut her off and raise the outdrive for trailering. 2 minutes later I see a quarter-sized spot of gear lube coming from the front of the lower unit?! WTF?
Here's a visual of where it was coming from, and it's the ONLY location:

I drained the oil (which was over a quart, blackish green, and had zero evidence of water) and proceeded to split the lower unit. There is a light coating oil from the area of the feed tube (yes the little seal was there), over the back half of the water pump, and then some down near the new shift shaft seal. Not puddles of oil but enough to get your fingers green. The drive shaft was dry but I did discover the first upper seal was shot, due to apparently being put in backwards! :facepalm:
Anyway, any ideas what might've caused this leak? I've been running her most every weekend and today was the first time I'd seen any oil...
Thanks,
TVB
