Sounds like you are going to dump some money into the company and need some feedback. I'll chime in my .02, I think there is a market for jet boats, I personaly have one and like it alot, however I am not one of thoes guys that is 'loyal to my drive' I one day want to try an outboard and my next boat hopefully will be a V-Drive. So my advice to you is, ask if there is a demand for the youngblood hull and rig them with other drives if possible, I am not to familiar with that hull, so I don't know if you can run v drives or outboards/outdrives with them.
