Identify sterndrive for a newbie

"Hi all,

I've recently

"Hi all,

I've recently moved to Michigan and have bought my first boat. I'm totally new to boating and the big lakes.

Can someone help me identify exactly what my motor and outdrive is?

It's a 4 cyl. Mercruiser Sterndrive in a 19', fiberglass, 1972 Cruisers cuddy.

So far, I've only found a couple of stickers on the motor - one with a serial number "3357601" on the valve cover, and another which reads "120" (I'm assuming this means 120hp?).

Other than that - that's all I know... can anyone tell me the CID of my motor, the type of outdrive, etc., etc.?

There's so many different names etc, when looking for parts, I'm not really sure what I should be buying parts for.

Thanks for any help!"
