Guys what size shafts would Yamaha f150’s need to be to hang on back of 1989 BW 25’ Outrage and what should the center be?

Per Boston Whaler - Twin engines for the Outrage 25 should be 20" shafts and 29-3/4" apart.

"The motors should be rigged with some toe-in with the spacing between the propeller hub centers 1/2" to 3/4" greater than the spacing between the leading edge of the gearcases. " -- Tom Clark
