Compression check on 1988 Evinrude 40 HP

[BondJmsBond]

I just replaced a head gasket and did my first compression check ever.
On a 1988 2 cylinder, Evinrude 40 HP outboard, I read 110 in each cylinder with a leak down check of very little psi for a couple of minutes.

Does this sound right, or should the compression check psi be higher?

Thanks

Sounds just fine to me.

should run great at 110. below 100 and then worry. a decarb has been known to bring it up even more, clean the crud out of the engine. the run seafoam in your fuel

you can use the regular seafoam in a spray bottle rather than Deep Creep it's the same stuff just not in areosol.
