Proper size compression gauge adapter?

[gunner1]

I'm looking into getting a compression gauge for my 1988 Force 50hp outboard but I want to be sure the proper size adapter is included. Can anyone tell me the proper size?

Don't know whart adapter you refer to, Gunner.

I think all guages are set up for 14mm spark plug holes, which your Force has.

SORRY!! It's amazing how omitting one little word can mess everything up. I was referring to a compression GAUGE to see what kind of shape my engine is in internally. I know that the standard adapters are 14mm and 18mm but I wasn't sure if either one of those would fit the Force 50hp outboard.
