The steering in the lower unit is pretty cool. Take away the expensive steering unit on the transom, and they're actually saving a bit of coin, and they only take up 1" more space on the transom than 400 hp. The price of one 600 is also less than two 300s. How long before somebody straps on to a comp layup Bullet that weighs 400 lbs. less? These are for big boats, though that steering tech and two speed LU is new and could be interesting if it trickles down to lower HP motors.
