Mono hull first run in river

Today I got out to lake Chachuma to run my boat in a lake and see how fast it could go. Well it is a reservoir, so of couse they said no. So then we went to the Santa Ynez rive and found a place big enough to run the boat. It worked pretty well, and was so fast. I still need to fine tune my weight balance so it doesn't porpoise. In the video I get to about 3/4 throttle. Before the video started I went to full throttle I porpoised out of control and flipped. So i am not trying that again till I fix the weight balance. Here is a video:
