It is the Tides brand. Unfortunately sans the spare shaft seal you see on the picture. But the good news is it has 100percent stopped leaking. I'm thinking there was some debris in the seal that somehow flushed out. Still plan to watch it carefully until I can get it hauled and the seal replaced just in case it wasn't debris.

Don -- your experience sounds 'alot' like ours! New-to-us 2004 Carver with twin engines & original Tides Marine seals a couple months ago... We went from "one seal drips some when underway" - to -- "it is dripping once or twice per minute sitting in the slip" -- to -- "every time I touch it, it gets worse and it is now a steady trickle!!"
Spare seals were installed on the shafts from the original installation, but I felt better at least short hauling the boat to attempt a seal swap out... once in the lift & upon consulting with TidesMarine & others who had worked similar scenarios previously -- we learned that these vintage seals had a bit of a design weakness.
See attached photo -- the seal carrying cases hose clamped into the blue hose would crack around the face screws - resulting in the carrier possibly contorting a bit when running, and causing leaks. Got some photos of the front & rear plates of said carriers - and bingo - on -both shafts-, BOTH carriers had cracks around MOST of the screws. One was leaking, the other - was a leak getting ready to happen.
So we backed the shafts out of the couplers (required heating the couplers to get the shafts broken loose BTW -- and we were fortunate the shafts were tapered - which made the removal and reinstall much easier. A split coupling would obviously be even better).
This may or may not be your situation of course. Tides redesigned the carriers a bit in the current generation, beefed them up by adding thickness in the area of the screws. I recommend a check around those screw threads on the front & rear parts of the seal carrier you currently have in place - before you go to the trouble of trying to slide back the shaft to get a seal or 2 put on....
Best of luck with it!, and please keep us posted. Hopefully you will still get to have a sweet Felice Navidad, with no more drama.
