UEW:
? Khanty: South (DN) čujət- 'ertrinken, zu Boden sinken, versinken', ?? North (O) suwilə- 'untersinken, versinken (ins Wasser)', (Kaz) šɔjtəŋ: šɔjtəŋ ǫχəʌ 'schwere, lange Rentiernarte (für Waren; mit Seitenbrettern und einem Brett hinten)', šǫjʌə- 'ver-, einsinken (ins Wasser, in den Schlamm u. dgl.; auch: das Boot beim Beladen); untergehen (der Mond)'
Commentary
The uncertain Ugric etymology listed in the UEW is problematic and implausible. As UEW notes, it is not clear that Hu saj- indeed reflects an old verbal stem. It should be added that the vowel-correspondences between Hungarian sajtó etc. and the suggested Khanty cognate are irregular. The semantic connection is also far from certain.
Conclusion
The Ugric etymology has to be rejected because of phonological irregularities.
