Clearly the combination of hull design, length, power and the ability to transmit that power into thrust have created the ability in this boat to porpoise.
Also it appears that Formula has picked an engine/outdrive angle that is very neutral. It neither allows you trim down to an angle that lets you plant the nose in really rough water, nor does it appear to need much trim up to reach the designed planing attitude.
No complaints, just not what I have experienced in the past and seems interesting/unusual to me, as most boat I have driven usually have a pretty wide range of trim they operate/tolerate. I honestly have no reasonable basis to say if this is common or uncommon, I only know what I have see personally and for my this is a different experience. And the experience that MeredithMan describes is pretty much how our boat performed, so it would seem to me there is nothing wrong with my boat per se, nor my surprise by the way it performed compared to my personal past experience.
Thanks!

Sounds to me that Formula has taken the stance that most people buying their boats, don't have a clue as to how to trim and adjust the handling of their boats. Thus, they have made things harder on those that understand how to make a boat perform they way we want.....
What this means, is that to really be able to trim and control the handling of your boat, you need to make more drastic adjustments, so that you get proper trim response... the problem is that would start to void a new boat warranty....
I would talk to a dealership or two, and see what can be done... The wrong answer from a dealership would be, "it is what it is"..........
Sounds to me, the the drive isn't really properly placed, thus you are porposing, because, you boat is riding on the hull further up, and the cavitation plate of the drive, instead of the rear pads of the hull, like it should....
