Between the bravo HP transom assembly and the magnum transom assembly?

The biggest difference is the pivot pins and the way they are mounted, the ring and the helmet aren't much different than the way the pins fit in them, it's quite a bit stonger. The earlier HP transom assemblies didn't have electric senders for the trim gauge and a trim limit switch to limit upward trim
