I have a 2003 merc. its a 15hp short shaft 4 stroke. I run my motor from just above freezing to the middle of summer so it needs a wide range of operating temp. any suggestions? sae 10w30? not sure. also where is the drain for the engine oil? i cant seem to get my eye on it and new oil wont do me much good if i cant get the old out lol/
