back in 2006 there was a thread on the old HB forums about an on-the-fly adjustable nozzle. Someone from Dana (Bob?) made this post:
"Dana Marine Products
We've produced 10 nozzle units that are out there. The one that was in HB was blue ano. I'll try to dig up the HB article. This part was initially designed to be a part of another much larger scale jet project. Some questions have arose as to how well it would benefit a normal jet application. If you're already running a place diverter, the difference could be minimal. It really depends on the boat, every boat reacts different to these types of things. The concept is that it would give you the ability to make several adjustments from the drivers seat while underway. These adjustments could very well take your boat to another level. In some boats, the differences may not be noticable. But in others, (probably in most cases) it will be a noticable increase in take off, mid range, and top end.
I can't say too much about this at this time, but what I can say is that within the next 12-24 months there will be a revolution in the jet drive industry. We have already produced and ran something that will change the way jetboats are viewed. Let's just say there's alot of room for improvement over all current jet drive designs. "
Whatever became of the "revolutionary" product? Was it a victim of the economy or will is still be available?
