46 Mercury Rear End Ratio.
 

So today just verified the rear end ratio. Got info for checking off this site.
One rear wheel jacked up, engine in 3rd gear, all slack out. Turned engine to get 2 complete turns at rear wheel. Engine turned through 3.5 turns so now sure the rear is indeed 3.54 as it should be. Could not see any numbers at diff housing. Thanks to those for supplied info on past post where I got the info.
