Walter V-Drive Light

Hi Guys - hope you don't mind me posing a question...

My Walter 26D V-Drive light came on today and remained on... across all RPM's. I had just filled the V-Drive with 30W oil before going out for the day, (it was a little low) so I'm wondering if that could have something to do with it (perhaps overfilled?). The boat is 2006 Calabria that I just bought it with 62 hours, so I wasn't expecting such issues this early on. Hoping to get back out on the water tomorrow, but a little hesitant with the light situation. Transmission oil is impeccably clean... and tranny fluid is full.

I do not believe either have been changed since it's still under 100 hrs. Was thinking of doing the oil tomorrrow to see if it helps. I've found various manuals online, etc... but nothing that shows where I could buy a pressure gauge, what type of gauge to buy, and how to install (assuming I wanted to test the real pressure, etc.. Wondering if it could be switch, or perhaps an overfill?

Any thoughts would be really appreciated?

I'm pretty sure autozone has oil pressure guages. You would just need the right adapter and hook it up to where the pressure sending unit goes.
