what should my compression should my 115 merc be

[JUNIOR PASION]

what should my compression be? i have a 1999 115 i had it tested i was wondering if my results were within par.

This isn't exact, but you're compression should be around 120.

What's more important, however, is the variance between cylinders...they should be within 15% of each other.

Hope this helps
