Finding the highest-scoring board with a 16- or 17-letter word is a fun, but very different problem. There are few enough "Hamiltonian paths" through the all the letters on a 4x4 Boggle board (~68,000) and few enough 16 letter words (~2,000) that you can enumerate all pairs in an hour or two.
Depending on wordlist and whether you want a 16 or 17 letter word, you get "charitablenesses", "supernaturalised" (British spelling), "quadricentennials" or "quartermistresses". These boards all score considerably lower than the REPLASTERING board. Full results here:

I hadn't realized until I did this "side quest" that most wordlists top out at 15 letter words. That makes sense for a Scrabble dictionary, but it's not great for Boggle.
