1970 Evinrude 25 hp lower end

[jakemueller1985]

Hey guys!

New to tin boats and i was hoping that the old, gray and wise may be able to steer me in the right direction. Im looking for some insight on the lower end unit of my '70 Evnirude 25hp motor. i found out today that it was leaking gear lube from what i believe is the water intake port. Im looking for a seal kit and possibly a better exploded parts diagram that would help me out in taking everything apart and what not. I drained the old fluid out this morning and it had water in it. The motor was stored in a temperature controlled environment this winter, nothing below 60 degrees, but before it entered my life i dont know how it was stored. Any thoughts and comments are welcome.

Thanks in advance guys!

Jake, welcome !!

if you plan on keeping that motor for any length of time,
it is highly advisable to purchase a parts and service manual.

the disassembly and installation is pretty straight forward
but can be intimidating if you are not handy with some
basic tools. There some some very good videos on YouTube.
and while you are in the LU, replace the impeller and seals.
