I had to keep adding drive oil to my boat today. It appears to be leaking into the engine compartment back by the transom. Looking at this diagram Bravo One XR (Drive & Transom) Mercruiser 0L914990 THRU 0W239999 Oil Reservoir Components Diagram and Parts

Will I be able to get any of those fittings in the back or does this job require removal of drive or engine?

Plan to dive into this tomorrow.

I recently replaced the lower fitting on my customers 25 Outlaw,,did not remove the engine, but I had to remove about everything behind the engine to get to it,,its a job,,these fittings should not be plastic.

Thanks for the reply 253. Not looking forward to it!

Make sure its not the Drive Bottle cap Itself .....or also the driveshaft seal could be leaking and dumping oil into the Bellows and then into the bilge ....m

Or the bottle itself cracked near the bottom. The plastic fitting? Into the transom assy? I used a piece of brake line from auto parts store.

It ended up being the driveshaft seal. Ran the boat for the 1st time since pulling the drive to fix the seal. Had the bottle go completely empty again but it has seemed to stabilize now.
