Perhaps some of you gurus would be kind enough to take me to school?

The configuration is unlike anything else I have seen. From the raw water intake, the hoses first go all the way to the front of the V-drive. The water passes through what looks like a cooler, before passing rearwards alongside the gearbox through a regular hydraulic gear oil cooler. There are two dipsticks on the gear box. One on the main body (the yellow round knob; regular gear oil, I assume), and one additional on this front assembly. Is there an separate oil reservoir for the V-secion of the drive? Looking at the dipstick it does not look like hydraulic oil, so I guess this is regular gear lube. Anyone know the oil spec I should be using here?
So my questions in short:
1: Am I correct in my interpretation that there are two oil reservoirs (one hydraulic for the main transfer and one gear lube for the V-section) and each circuit has a separate water cooler?
2: The gear boxes appear to be running well, but I am unfamiliar with symptoms to watch out for. What typically fails - if anything? With all the oil cooling going on, I assume overheating is a potential issue, but how do I monitor it?
3: How often do you change the hydraulic oil?
4: Anyone know the oil spec I should be using on the front reservoir?
Thanks for your patience with a V-drive rookie!
And, yes, the shaft seals are due for a clean-up. Shafts are going out for tidying and repacking as we speak.
