Has anyone converted from the horizontal through bolted aluminum "L" brackets with the standard black engine Mercury pedestal mounts to solid offshore mounts in a 2003 Checkmate ZT 260 (or similar boat)? Mine originally had a 496. I am upgrading it to a new custom 565CI BBC. If so i would like to know what motor mount you bought.

I am measuring 25-3/4" between the stringers.

Thanks!

my 253 has them..in the boat when I got it...super strong...but I bet would be a super pain to set up the 1st time !!
