Hi there,

The lower unit on my 1972 80hp Merc has got a crack in it, and if it's
filled with oil, all of the oil will eventually leak out of this crack.

What options are there for fixing this?

What kind of costs do you think would be involved?

Cheers

Sell it to Clams for parts. I would think that fixing it would be much more
costly than the value of a 30 year old motor.
