Hi new to the forum and hoping I can get some help. Does anyone have a part number for the lower unit input shaft seal or could point me in the right direction to look it up. I do not see the manual or parts for a Sea King on this site. All help would be appreciated. Thanks!
 
The seal in it is really old and I am struggling with even getting it out. (Any suggestions to get out would be helpful) Likely is going to come out in many small pieces. No number on it that I can see. After reviewing owners manual online and model year charts, it is a GG9021A Mod 12D13. (The serial number plate is missing from the side of the mounting bracket)
 
Below is what I found for seal kit for 1960 johnson 18hp. Not 307563. The Sea King/Gale manual has cut away diagrams but no part numbers. Any idea where to find the actual Sea/King Gale part numbers?

SIERRA
18-2684 LOWER UNIT SEAL KIT

Equivalent to:
GLM: 87606

Use a puller, or go at it with picks/screwdriver/hammer, but error to the outside, DO NOT damage the shaft surface or risk the new seals getting immediately hosed. Just be careful, slow, methodical and you'll get them out...
