What were they thinking?

[Jet Hydro]

I`m having a hard time trying to figure out what Hondo was thinking when they made these Hydros. There`s over 3/4 of an inch angle difference between the front of the intake than the back.("up" in the front) I can now see why I run out of water in the first 1/8 of the 1/4, way to much angle on the intake. As the sponsons lift, the intake sucks air.....
This could be fun to fix.
Kinda makes for a hole new ball game from what we first thought was wrong.

That is strange. When was that hull built? I wonder if someone designed a jet hydro today, how would they do the bottom in relation to the intake. If I were you, I'd give Jeff Bennet a call to pick his brain about your hull, and see what ideas he might have. NASA did when they wanted to know what happened to the space shuttle when it blew up last Feb. They hired him, as well as other aerodynamic experts to figure out what happened. So, if NASA wants his knowledge, I think it would be wise to just see what he says. Just an idea
Thanks for the photos. keep us posted

I had a few ideas that I was going to do but after we turned it over tonight they all went out the window.
I`m willing to talk to just about anyone at this point. I cant believe I had it running in the 11`s like it is.
Time to rethink and start from a different angle.

Isn't that the truth...

What intake did you take out?

[Unchained]

I don't know what to think about a hull design like that but the angle certainly lessens the curve that the water has to make going into the pump.
What if you left the intake mounted at that angle but built a large keel bubble in front of it?
What was your intake pressure showing at top speed?

Unchained, I don't think I don't think he needs to put a very large keel bump in though he might have to increase what is already there somewhat.
A hydro jet is designed to ride on the front sponson plates and the keel & ride plate (a device that was developed after that hull was made) ... essentially a three point ride. In order to set a hydro jet up properly a good bottm man would need to know what intake is going to be used (need to know what depth down into the water it will be) and what Hp the motor going into the boat will be (this will determine the general size of the keel bump that will be needed). The trick in getting a hydro jet set up to run stablely is to match the front sponson plates depths to the keel and ride plate ... This I might add, is one of the most tricky types of hull types for a bottom man to get set up right ... Not impossible, but, requires paying close attention to details ... down to the thousandths.
Some pictures, including closeups, of the actual intake (and its straits) to be used (just set in place, not glassed in) would be quite helpful.

I thought hydros were designed to run props and carry the tail out of the water on the prop. Thats why they wont go very good with a jet, you can't unglue the tail. Put your blown motor in a tunnell hull and see how much better you can go. 11's should be considered slow with a blower motor.

There are Hydros (For V-Drives) and some Hydro Jets ... The Hydro Jets are a tricky breed to set up and take patience ... That may be why there aren't too awfully many.

The pump was a Dominator when I bought the boat so I would guess that the intake was the same??? We are going to install a new Aggressor Low Profile intake as soon as we can figure out what to do to the pod. I`m going to make a few calls to the pro`s and see what they think.
