Change oil on sportsmaster
Hello.
I wonderd, how does one change the oil on a sportsmaster lower unit?
I cannot see any plugs at the bottom of top of the lower unit. Are they behind the steel plate above the caviation plate?.Last edited by killerpirate; 12-04-2020 at 10:15 AM.

Note that you have a sportmaster with a straight skeg. That one is for twin engines. With a single engine, your boat will not go straight.
The drain plug is still below the prop shaft, thoughMarkus' Performance Boating Links:

The skeg for singles is longer and has what is called a torque tab: It is thicker on one side to add pressure from the water to compensate for the torque from the rotating propeller.
if you have two counter-rotating engines, the propellers cancel each other out and you don’t need torque tabs. That is what your lower is for.Markus' Performance Boating Links:
