I have what I assume to be a very early 1952 Lightwin. The serial number (03700) is the earliest I've seen. I've gotten a lot of good information from reading the other threads on the 3012 but I can't find any mention of the problem mine has.
I'm trying to replace the prop and main shaft seals (aka oil retainers) in the lower unit. According to all the literature I can find online, both seals are SUPPOSED to be p/n 300599, which is a lip seal with a 0.425" shaft size and 0.875" bore. Sierra Marine sells it as 18-2035. That p/n is correct for the main shaft seal but is TOO BIG for the prop shaft seal. The shaft dia. is correct at 0.425" but the housing is a 0.750 bore, not 0.875.
I've checked many online seal catalogs and can't find a seal with this ID/OD combination. I'm considering using a metric 10X19 seal but it's not the correct seal, obviously. Has anyone run into this before?
Thanks,
