I have a problem-- this thing stinks.

I mean literally. It is the most horrible, putrid smell you can imagine. I can only assume that the gear lube that was in it needed changing about 5 seasons before the last time it was used. We've obviously drained it, but there is this smell that we can't get rid of. As such, the admiral has banned the outdrive from the garage and it now has to reside in a shed for the time being.

What can I use to get this smell out? I was thinking I could pour in some mineral spirits and let it drain back out, hopefully taking the film of remaining gear lube with it. Obviously the goal is to take it completely apart and clean everything, but to do that requires reintroducing the smell into the garage, which gets in the house, which gets me in the dog house. So I am trying to find a way to "rinse out" the funk so I can return to working in a climate controlled environment.

Gear lube smell is something we learn to love.
Flush some diesel fuel through it if you want.
That will tone it down.

Be careful about flushing, you don't want any left overs in there thinning out your gear oil when you're all done. I would just put fresh fluid in, run it on the muffs in fwd/reverse (with prop off), change it one more time and be done with it. Once it's sealed you shouldn't smell anything other than what's left over on the outside after wiping it down. I would think the smell will go away eventually.

We are completely rebuilding it, so there won't be any left in to thin anything out. We are taking it down completely and inspecting everything, so eventually it will be wiped clean inside and out before being reassembled. I just need to be able to flush as much out as possible, along with its smell, so I can move it back in to the garage to finish tearing it all down.

That's a plug for the drilling of the water passage.

Possibly, or the plug may be under that lot.
