Here is a pic of the 40 raptor mid drive change to our WMD drives. I will let Andreas know about this site so he can post more pics.

As you can see in the backround, they have been busy setting up shop.

Nice! I was looking for a few good pictures that I had of Vern over in Avalon in the v, but haven't figured out what I did with them yet.

Those drives are SOOO cool. What kind of speed increases are you anticipating?

+2

How do they compare to the # 6 in weight and x-dimension height?

I "haven't" seen them in person. The are (from what I "hear") cool as an MF'er... I was blown away when I "didn't" see the inside of one... Pat, was that cool? I didn't see anything... :D

But I'd buy one in a second if I had the cash and if Pat's mom didn't tell me that my boat was too small to run one! :sifone:

Oh and I'm sure Pat will answer, but I'd guess lighter and more durable with a similar X.

The x dim is fixed at 15 inches input to output. We change the internal height by making a drop box to retain the engine position. In a perfect world we move the engines down also. On the platinum we have the engines over 5 inches lower then the drive input in the boat. The offset box was 9 inches with the 6 drive. The vertical cg is a little looked at factor in "modern vee bottom boats". When we had the bravos on this boat we had 7 inch drop boxes in it with the bravos.

We normally dial in the x on the boat with a 6 drive for a baseline like we did with the platinum. On this boat we are running a very high x dim. I cut the cav plates off the 6 (max 18 dia) for the big diameter props and extended the skegs to put the stability back because of the high x.

The performance gain expected is the 400lbs left behind and the ability to run any gear ratio and prop diameter we like for acceleration. For now we ran the same set up (prop and ratio) to get the ballance back (baseline -400lbs)

The cg is critical on any boat and propper testing. I will keep the updates coming as we test.
