Correct oil?

[bowhunterjac]

I'm in the middle of getting things together to change the oil on my Mercruiser stern drive. It's an Alpha 1, 3.0 The owners manual calls for SAE 40 weight oil, which I bought. However the filler cap sahows to use 10W-30...?? Any suggestions?

Also, I'm having some issues finding the correct filter. Right now it has a Mercruiser filter on it, is there a way a way to cross filter numbers to get what I need at a local parts store?? I know they can do that with spark plugs etc... But they aren't having any luck with the numbers I can read off the filter.

Thanks..!!
