I started a batch of mead on 11/13/16 with the following:

18 lbs Orange Blossom Honey
Lalvin D-47 Yeast
Water to fill 5 gallons
OG: 1.122

I added yeast nutrient at pitching then each day for the next 3 days (not sure what nutrient or how much, just the amount that came in the kit). Fermentation temperature stayed at around 60-64 degrees F for about 6 weeks and it was fermenting VERY slow. So I warned it up to upper 60s and it fermented for another 2-3 weeks and stopped. I let it set until 2/25 where I racked to secondary. At the time I racked, SG was 1.041.

I just checked it today and SG is still 1.041. According to the instructions in the kit, FG should be 1.020-1.022. So, I suppose fermentation never completed.

At this point, is it a good idea to try to pitch more yeast to finish fermentation? I do plan to take a ph reading first to make sure there aren't any issues there that need corrected. Also, if I do pitch more yeast, should I rack it again first, pitch with it sitting on it's current layer of sediment?

On a side note, I did taste it and the taste and aroma are just fine. There aren't any off flavors or scents.
