Actually I looked through my collection of Mercury brochures, and the first year of the 3 liter the 225 carb (1994 year) had a ratio of 1.64 to 1. After that, all of them (even the ones being made now for overseas users) are 1.75 to 1. So unless someone replaced my LU with the old one, it's not possible that Bigshrimpin's outboard turned a lower gear ratio than mine. If anything, it's more likely that he turned a higher gear ratio
