I don't know if I'd say a 22 is "easier" than a U19. Two totally different handling boats. The U19 will chine walk in flat water, which you can learn how to stop. But, it will never porpoise even without any tabs and too much trim. You also have to REALLY try to launch the bow into the air, as it won't do it unexpectedly. Pretty much the opposite of a 22.

Maybe I missed it, but what prop are you running?

Also, is your boat yellow?

No, my boat is white with single red deck stripe / small red hull stripe. Running 25m+

There's been a couple changes through the years but I really think the slow speed handling things could have been addressed by Donzi but they never had any interest in doing so.

There were three main changes through the years, the switch to a reverse chine, re-spacing of the stringers and inner lifting strakes, & X-Dimensions moving down then back up.

Most of the changes happened during the era when AMH owned Donzi but I don't recall when the reverse chine change actually happened. The stringer/inner strake move seems to have happened around the time when Donzi and Merc switched to the 496 engines but we never really figured out why since a BBC is a BBC. As far as X-Dim's, the X's were quite a bit higher before AMH then AMH dropped it down to a fairly low standard dimension for years. It wasn't really until around 2002 that they seemed to entertain the idea of moving the X back up for performance. Once the 22-Shelby boats came out in 2006 Donzi seemed to be comfortable with putting a 22 on the market with a 2" raised X-dim.

At one point I asked one of the Donzi factory guys why the 22 handles like it does. His response was that it's just a big rocker hull & does what it does at slower speeds.

Mine is a '99 with a reverse chine.

Thanks for the education. Is a 2007 a good year as far as hull design elements and quality? I read some where that quality suffered for a brief period , not sure when or if it was even true. I followed the market for a while and bought mine because it appeared to be a fair deal . I really didn't educate myself as much as usual ( or I should have) on the specifics of manufacture. I actually just wanted to stay away from the omc era stuff for ease of parts sourcing and resale . Also what entity owned donzi in 07 ? Thanks

FWIW, the M+ is squirrely on these boats IMO. Fast, but.. A Turbo will settle it down pretty well and usually run as well or faster than the M&

Took the time to read the posts, and I agree seat time and prop testing will get you there. The 22 has a "flighty" bow and there is a fine line between fast and launching the bow.

My Pantera 24 was the same way, and a Rev4 prop handled much better than a Mirage and Mirage+. I also had a Turbo lightning that handled well for a 3 blade and was almost as fast as my Mirage.

Got out today , det river from wyandotte to lake st clair . Played on the lake for a bit then headed back to wyandotte. Water was kinda snotty on the lake. I spent a good deal of time running without the tabs , and some time with. The boat is happy running with little or no tab (over 35 ish) especially over 50mph. It feels great at speeds of 60-65 in the garbage I was running in. The bow is certainly happy to launch like others have said. I am coming to realize that the boat will probably act fine in most cases , I just don't have the seat time to know for sure yet. So I get an uncertain feeling here and there. I'm sure it will go away with more time. As for the slow speed rolling, I am confident it's because I wasn't feeding in enough throttle mid turn . I'd loose speed and start to fall off plane. If I drove into the turns the boat just carved away . Alot like riding a sport bike in away.

I have an 18. All the stock props I tried out had bad handling. I would consider giving Brett at B-Blades a call. I got a pair of props from him for my old Formula. When I sold that boat myself and my friend both tried them on our Donzi's. Not only did he gain 5MPH at top end (I don't know what I gained because my tach is currently flakey so I am not pushing it) but we also are both amazed at how all the bad behavior of the boat is gone. They both run much flatter and ZERO chine walk. Props are amazing things and can completely change the way the boat works.
