NEED HELP! - 1964 hydrodyne oil seal/o-ring for prop

I have just finished restoring my 1964 hydrodyne. Pics up soon!!!! It's been out of the water for 2 years now getting beautified.

I got her in the water this past weekend, and noticed a minor oil seap by the prop.

In looking through the owners manual for Eaton out drive, it's looking like maybe the oil seal and o-ring.

I'm no boat expert and would greatly appreciate any input as to where to find these parts or if this is even what's wrong.

So I've uploaded what I think is wrong and it's #4 & #5.

#4- E-25091--- oil seal

#5- E-25092--- O-ring

 

Here she is in the water!!!!

 

that looks beautiful!! i wish i could fix mine up. what year is yours?

 

o i feel stupid. i just read it again and saw 1964. haha sorry. i think that is what mine is. or at least in the 196o somethings. anyhow, your boat is amazing. i would like to see the inside. more pictures please
