Boat talk—7.6L V12 outboard motors

Holy cats.

https://www.soundingsonline.com/feat...s-largest-ever

At first I assumed it must be a twelve cylinder evolution of a cam in block LSx, but nope! It’s a quad cam 7.6L, based on Mercury’s 4.6L DOHC V8. My initial thought there was Ford or maybe Volvo (didn’t they punch that V8 out to 4.6?), but other reading suggests it’s a bespoke design based on their V6. And it sounds like for packaging reasons it’s a hot vee.

You're an intersting one, JST... On the one hand you've fully embraced the EV movement more than almost anyone else i interact with, on the other you love yourself big, powerful ICE monstrosities. Kinda Neat.

I'm sure you've seen this before, but in case not, there's an australian company that makes custom LS based V12s:
