Ya we will see. I'm more interested in seeing the NA DOHC motor that will make around 850-900. My guess is 2 year warranty and 500 hours before rebuild. It will do to the I/O market what the 400 has done.
PS- Dale those 500s on your boat will just be flat out awesome!

I wish the HP increase were real as well as available before my order is placed. According to the CNC verado prop guy at Mercury racing, it only a rumor. It only logical that they evolve this platform to higher levels since they are selling so many.
You can't just increase the boost by changing a pulley like someone said in this thread. The boost in controlled by the ECU and the SC is setup to run at full capacity and then boost limited in software. This ensures a constant 400 hp to the prop under most all conditions. The boost can be raised through an aftermarket tune already offered, but the design limits the increase to only 25hp. Going higher requires a larger whipple SC as well as other changes from Mercury.

, so it's not a slight towards O/Bs, of which, we own 1 now. Our next boat will be either a diesel powered or O/B powered.....

not so fast Phil keep in mind all this power is pretty linear through shafts (which easily handle the power) in a straight line only making a direction change a single time at the lower and in outdrives like bravos the upper is the weak link, the lowers are pretty durable, if the lowers on these are adapted XR stuff it would fall within range i would think.

I hate to throw a wet towel on this campfire. But this is a Photoshop deal. The last time Mercury had a big outboard release was the 400. I got four of them before the show. We have no 450's. We have no 500's. Be prepared to be disappointed at Miami if you actually think this is happening.
