Not quite true! the SC10/B4.1/T4.1 all use a different gearcase and T piece as the outdrive bearings are a different size (metric) - the 4.1 ball diff and the sc10 gear diff both fit these casings with no alterations required
This means that they are not compatible with the old B4/T4 outdrives/casings
B4 gearcase #9574
B4.1 gearcase #9826
B4 T piece #9570
B4.1 T piece #9818
Hope this helps
