Been doing the rounds for a while, as usual, everyone "knows" heard from a friend of their uncles sister.....so far, full electric 600HP+, diesel electric, azipod drive on the bottom of a conventional outboard, a V10, a V12, a new 500HP V8, someone has to be right, eventually.
edit, I forgot, a supercharged V8 putting out 628HP, and Mercury buying Evinrude and making 2 strokes again.
