Greetings To All<br />I bought a new Nissan 9.8 4 stroke last summer. Its my first outboard and its been great. I followed the winterization instruction from the manual, changing the lower gear oil, the engine oil and spraying the fogging oil through the spark plug port. So I'm planning to take the boat out tomorrow and the instruction manual calls for running the engine for like 20min through various speeds and then change the oil. My question is after running the engine, does Nissan mean changing the lower gear oil as well besides the engine oil? Thanks for replying.<br />James
