^^^^ there are as many boats in the pipeline waiting to come out with the 400's than are already on the water. So far in the press there is the DCW32, the Skater Nasty's 308 not yet in the owners hands but run @ Mercury and the Skater 3208 that was previously triple 300x's (not XS prior to re-rigging the 400's)

400's are more weight than the 300's so you have to consider lbs/hp for the entire package

Anyone out there with a 28 that would be interested in a really nice Superformance Cobra, plus cash trade? 351w stroked to 402ci with an Imagine 8 stack injection system. Here is a link to pictures. I also have a Serpent Express, enclosed, hydraulic tilt trailer made especially for the cobra that can go along with it. Thanks....

Using the speed calculator, the extra 200hp (factoring in an additional 600lbs in weight), gains you 9mph in top end.

You cant really use the 32 skater, because its way to complicated to go from 3 motors to 2 and have a fair comparison, or basis.

I think the 28 DCB gained roughly 10 mph- but again, is that an every day 10mph, or a setup for top speed number?

The 318 skater has never been tested with any other motor- so once again no benchmark.

DW 32- many boats with 300's have been around, I've heard 115, now 124 but a light basically race set up- that'd be a gain of 9mph.

Seems to me that the real gain is only 6-8 mph.

four strokes are the future due to uncle sam and the tree huggers around the world so we just as well embrace it I suppose. Now how long till someone can take the 400r and bump it up? anyone know if the sportmaster lower go any changes when they mated it to the 400R or are we still going to have the water intrusion issue?

I believe we are on the same page here. There is performance in the engine but there isn't enough of them out there to say that it is the "Go To" engine of choice.....but its always good to say you have 400's on the back vs. 300's....

any of you guys that are in the shops or know the guys in the shops should be getting some feed back by now from the CC's. they have quite a few running them...some harder than others

With all my know which is not much I am sticking with 300's for now. The word on the CC's is that the old 350hp Verado was faster than the new model by a few but ran higher octane. So the difference between the old 350 and new 400hp was only a couple of MPH on the big boats.
However new 350hp verado gets better fuel mileage than older 300hp verados. I think for guys with big money to spend they want the 400hp badge on the transom whether it is faster or not.

I feel confident when done my 30 will run very close to a 400 powered boat for a lot less money and handle better in rough IMO.

On a different note- the new 400 ROS, which is dry sump, puts out the same HP as the 400r? It would seem that there should be SOME hp gain going to dry sump, and some hp gain, having the exhaust blow straight out the back, above water as mercury is calling it. That motor has some visual wow factor to me. Looking forward to seeing it run this weekend in Xcat

Oh man- KTRON is going to be looking for you this winter

Yeah me too. Spoke to Daren the other day. I am sure the DW will be faster than the Skater but my point is same boat for boat with 300x power vs 400hp verados. Hope to hook up with him on FL West Coast.
The DW race guys say the 32 runs 118 with 280's. 120 with 300xs's so what's the big deal with 400's at 124.
I am sure a 300x is more than 4mph faster than a stock 300xs as my boat is a perfect example of that.
So how fast would a DW be with 300x's???
I bet somewhere very close to 124.
But if you got 50k for motor package and like the warranty aspect it is not a bad option.
Lastly if you guys have been following the 400 swap over on S&F that boat has been done for a few weeks now it has been very quiet. I can tell you they are still working on it and were far from happy with the results thus far vs the 300x.
