Replacing head gasket in 3.0 mercruiser

[flournoyg48]

Is there any difference in head gaskets when buying them online. Like are they all the same size or are there different shapes

You should specify for marine use.

 

[Alumarine]

The Fel-Pro number is 17000 for the head gasket alone or
17200 for head gasket, rocker cover gasket and valve cover gasket.

the 3.0 is an industrial engine or a marine engine only. make sure to get the marine head gaskets
