Sierra Low Unit Seal Kit Charts?

[Buccaneer]

Anyone have a Sierra lower unit seal kit chart / list for the 50’s & 60’s OMC
outboards? The only one I have is for much newer units.
Thanks.

Buc – here’s one on Marine Engine that goes back into the 50s and 60s.

Thanks Bob. I thought ME might have had info., but I couldn’t find any link
to it on their homepage. Bookmarked now.
Strangely, they don’t list a seal kit for a 1956 QD 10 hp that I may be
working on for my cousin.

Nope, that has that prop shaft seal that Sierra doesn’t have available

Also OMC’s version is N/A anymore either.
Looks like the best bet is a CR 6280

	Inches (IN)	Millimeters (MM)
Shaft	0.625	15.88
Bore	1.250	31.75
Width	0.313

National Seals #471264 also works for that size shaft and housing bore, but is 0.250 in width and their #470018 seal is 0.375 in width.  The CR seal you found is likely the closest fit to original.

Thanks Bob, I ordered the CR 6280 last night.
