Working on servicing the BF8D that came with my boat - same one I posted about remote steering.
After a fair battle with the drain bolts (impact driver and some heat got them off), I’ve managed to drain the gear oil from the lower unit.
It is very milky, so looks like water has got in. I’m aware that for some time before I acquired, the engine was left in ‘lowered’ position with prop etc in water, which can’t have helped.
I’m assuming a seal, or more than one seal has gone bad.
Looking at the diagrams here:

and here:

I’m trying to work out what the different seals I might need to replace are.
It seems there’s a large o-ring seal that goes round where the water housing fits:

Plus seals around shaft (parts 25 and 26 in the water pump diagram).
Are there others I’ve missed? I think i saw some threads mentioning seals around the prop?
