The Premium is for 75 hp & under; the High Performance is for over 75 hp. I have used the High Performance gear oil in my Cobra for many years with good results. Local price is about $17/gallon. Used to be $11-13 or so.
Pennzoil also makes a marine gear lube for lower units I’d check if that’s available where you are….
