Royal Purple makes Synthetic Lower Unit Lube & has a new Synthetic Motor Oil designed for 4S OBs... Good stuff... My Honda BF-225s are >10% more fuel efficient vs. when I used regular oil/lube...Not sure where you get it where you are, but it might be worth hunting...

Have used Yamalube 10w30, no synthetics, have about 2500 hrs. on my F250's, with no problems. A bit hesitate to switch to synthetic. Mech. supplied oil in the past, now I need to. Thanks for suggestions. Know Bonita Boat center people are good folks, may try them, a bit of a drive for me from Ft Myers.
