Hello All,<br />I just picked up a 1970 Sears 7hp outboard. ( ESKA)<br />Thanks to the resources of this site I have ordered a shop and parts manual.<br />The motor runs strong. It needs a new prop shaft seal which the previous owner included,but did not install.<br />Questions: How do you replace prop shaft seal and what kind of gear oil ? Recommend any other web sites covering this brand ?<br />If the seal replacement is too detailed to get into over the forum I understand. I was looking to fix it this weekend.( manual won't show till Monday)<br />Thank you,<br />Max
