Default Crazy tunnel view video at 170mph

I thought it might be interesting for you to see, when we test the X Power Drives we rig almost every boat with the drives with video cameras all over to help us understand and maximize each and every boat. This is a Spectre 32 and you can see it had a porpoise from 85 to 95 and we suspected it had to much weight rearward of the cg. In the video at this speed you can see it pack air and lift the boat then as if falls back down it re-seals the rear only to do it again. Then after 95 it seems to pack enough air to keep it up completely. Also you can see how much boat is actually touching the water at 170mph (not much) and this is with a positive .5 degree of drive angle. We also have tons of underwater videos as well as others if your interested.
The boat starts moving at 1 minute into the video so just pull the bar across.

Sure beats the excitement of hanging your head in the tunnel for a look see.

Interesting to see how much water is pushed forward while still at slower speeds, then all of a sudden, daylight can be seen.

How far back was the camera set?

The camera was right at the trailer strap eye, and hung down about 5 inches.
