Leaking Stern drive oil where does it go?

[lknlover]

I just had my yoke seal (gimbal bearing, and bellows) replaced on my Bravo 1 outdrive which eliminated most of the disappearing oil but we're still losing 1/4 inch per ride so we now suspect a prop seal leak.

My question is if it is the prop seal would any oil at all be going into the bilge? We have a small amount in the bilge as will as what I suspect on the back of the boat. The back of the boat does get black but not this black. We're also noticing a bit of oil in the water after running but wonder if that might just be exhaust

Mechanic is scheduled to come back and do a pressure test while on boat as first time pressure test was done off the boat. It's been weeks and we want to be sure we're not doing more damage by running it.

gear oil in the boat only comes from the yoke/yoke seal area. a prop seal just dumps it in the water.

Pretty much what Bt Doctur says.... except if you have a gear lube moniter. That can be leaking anyplace from the plastic itself anyplace down the line to the transom plate.
