out drive leak from 140 merc i/o

[1973delta]

I have a small very slow leak that leaks from the forward part of where the upper and lower unit meets when it is trimmed up. I not sure if i forgot something when i changed the water pump for the lower unit. Any ideas

Quad ring between the upper and lower comes to mind in that area. Did you glue it in?

What model outdrive? Quad ring seals the upper and lower housings together so the gear lube can pass between the two. Many glue them in so they don't move on assembly.

its a pre alpha. Is it the little o ring that rides on the outer edge of the lower unit case
