Re: NEAR NEW 8HP YAMAHA high thrust
If you mean lower unit gear oil, it is located on the lower unit, starboard side (looking towards the fron of boat) there will be two screws, one down near the end of the LU, the other just above it. unscrew the lower screw first, have your container ready to catch the oil, it will run freely when you remove the top screw; fill from the bottom screw until oil runds out of the top screw; make sure you use a new gasket for both screws.
