Evinrude 3012 Lightwin prop shaft seal

[todd281]

My manuals do not cover this model , Could someone confirm that the prop shaft seal to fit this motor should be # 300599 [new number 327031] Thanks

Hmm . That says the 300599 is a good number. I guess the seller sent me the wrong seals. Just my luck.

Old number 300599 is superseded by 327031 (or Sierra 18-2035). So what did you get?

314167 were used on ’68 and later motors. Is it possible someone switched the carrier and seal in the past?

The very early Lightwins and JW’s produced did use a different size seal on the prop shaft and I believe it was the same one used on the Johnson TN 26-28’s. They were probably using up old parts first again. If you can post the serial number, it will help identify the year it was made.

just measure the shaft diameter and the seal seat ID diameter … select the approriate one from the seal chart I sent you

Wow , The seals I got [all 10 of them] are the 327031 seals . they are the same size as the 18-2035 seal. However, indeed they do not fit. The OD of those seals is 0.875. The bore in my housing measures 0.740. I thought that maybe I did not get the metal outer ring removed from the old seal but alas the bore is clean. So I ended up chucking the housing up in my lathe and opened the bore to 0.873 so the seals I bought will now work. I hated change from OME sizing but I could not find a seal by size that I thought would work. Thanks for all the replies, Happy Holidays to all
