Yamaha F115TXR head

[Sedge]

OK, I know this is a pretty basic question, but: How do I tell whether my F115 has a stainless steel head or aluminum? I haven't found any specs on the engine that state this info.The 10 micron fuel filters are specific to SS or aluminum.

put a magnet on it.

Except neither of these materials are magnetic...unless the stainless part is an insert into cast iron(?). Anyway, I'll try it. Thanks
