Impressive 557 hp., wonder how much $$$, cant be cheap. Great idea with the ZF trans. They weigh a bit at 1k pounds. As a comparison I use to run a Mercury Mod-vp V6 racing engine that was around 350 lbs with 260hp. Seems nothing compares to the HP to weight ratio of the old 2 strokers!

Thats really not bad considering that a Yamaha 350 weighs in at 822 lbs on the 30" shaft model. If you could go from quads to twins that would save you almost 1300lbs . which could offset the the HP power difference of 286 hp. I dont know the yamaha's torque specs though so the performance difference is a little hard to guage. The 1300lb weight savings is the big deal though, that is a huge amount of stress taken off of the transom.
