I’m wondering if anyone can help ID this dripless seal? The pipe on the brass/bronze part leads to an oil reservoir above the waterline. Bukh?

Asking because the next step (once I know what it is) will be to try to find service/maintenance recommendations - so if anyone has suggestions those would be very welcome (no issues with it to date but not something I want to risk failing).

My Buhk installation had similar. Only problem was that the old installers had placed the oil reservoir below waterline so seal dripped and reservoir filled with oily water. Seal clearly was partially lubricated by sea water as sort of worked.
When prop tunnel detached from hull we put new ceramic disk seal which is theoretically maintenance free but can leak if mud gets between plates
Almost all boats leak somewhere

Thank you both for the replies, much appreciated. Presumably if they aren't all standard I can't make assumptions about the size of the seals - so it'll be a case of taking them off, measuring the old ones and getting suitable replacements? And taking them off would involve loosening the jubilee clips, separating the shaft from the r&d coupling then sliding all the seal parts off the shaft?

Youve got it. However while you are about it keep measurements so you can consider changing to a different seal type ((shaft sizes,)
