Compression for 25 Mariner?

[alloycowboy]

I just did a compression check on my 25 Mariner (1988), its was pretty low. 50/53
I did it while it cold, I cant get it to start to warm it up. So more or less it needs a overhaul?

My guess is a blown head gasket between the cylinders, cowboy. Not likely to need major surgery.
