How much does that brick weigh?????:D :D

Seriously though, what rpms are you spinning the 23's????

For comparison, My 32 AT weighs about 7800, has 1.36 drives with 415hp/502 mpi mags. I spin stock 24 Bravo's 4700-4900 depending on fuel to about 70-72 mph.

When Mercury list a gear ratio of a drive, it's always the overall ratio. To get that ratio you have to take the upper ratio times the lower ratio. That will get you the overall ratio.
