The box enclosure should be about .737ft^ of space (including the displacement of the sub). However, the box you made is about .41ft^. Either get a different sub or make a larger box.

what would the negative effects be from using this box? I cannot make it any bigger.
you are roughly .3^ft. shy of what you need for that sub, odds are it will emphasize a higher frequency range than it normally would in the proper enclosure... In other words it will make the sub "peaky" and won't hit the lower notes as well...
If that's absolutely as large as you can go, use some polyfil in the enclosure. The sub will perform as if its in a larger enclosure.(from what I understand) There are charts to tell you how much to use or maybe someone with more knowledge on the advantages of polyfil can chime in.
yes, polyfill will help, but there is no amount you can fit into .4^ft. enclosure that will make it .7^ft., that's nearly double the size, it's just not possible... Also be careful as being in a smaller enclosure will already have your sub running hotter than usual and polyfill increases this effect so it will run even hotter yet... Your sub will also be more power hungry for the same output as you would see in the larger enclosure with less power, so be mindful of this. If using polyfill make sure it can not contact the sub at all or you could potentially have a fire issue if it gets hot enough...
Agree. You are almost half the size you need to be. The box will not dig very low at all and no amount of polyfill will be able to be stuffed in there to increase it enough to fix it. If you had say a 1.75ft^3 box and needed it to be 2ft^3 you could "trick" trick the sub with polyfill but not if you needed a 3ft^3 box if that example makes any sense.

Well shoot. Does anyone know of a shallow 10" that will work in this box and sound good? With a minimum of 200w rms

Well the subs came in the mail today and after reading the installation manual it says the recommended sealed enclosure volume range is .50 to .75 so I think I will be close enough.
I am in stereo car sound system business for over years and according to your requirements, yes it is perfect for your sealed box.
