Hi Guys. I know a lot of you don't have V-drives, but was wondering who does if anyone has any info on hp/Tq ratings for a ZF 63IV. I looked up the specs and it reads this. Currently I have a couple 8.1 375hp in my boat. Boat weighs around 15500 dry. if I was to upgrade the motors I'm wondering how much I can push the trans. Of course I will call ZF when I'm 100% ready, but was just wondering how much you guys are pushing through one. Thanks

Maximum input**
Pleasure 524hp at 5500rpm
Light 499hp at 5500rpm
Medium at 425hp at 5500rpm
Continuous at 201hp at 5500rpm
