Model 74 originated as a private project of the company Boeing, to develop a F2B-1, and in the original form, it very much resembled. He had, however, the chassis of the matching FB-5 and mainly counted with the possibility of operation in wheeled and float version. At the same time entered four projects float tank, in addition to the elder Vought FU-1 also Eberhart XFG-1, Wright XF3W-1 and the Curtiss XF7C-1, all also using the system one float and two auxiliary on the edges of the wings (unlike the float variants FB-5). Navy type tested as XF3B-1, but was only loaned and did not get any military designation. In its original form did not, his performances were weak, therefore he was returned to the factory, which converted it into the new Model 77, zalétnutý 3. February 1928. Was extended bow, due to better maneuverability at higher altitudes to get a new upper wing of greater span with the external parts with mild arrow due to better longitudinal stability, has been modified and the tail, with the new rudder shape corresponding to the serial F2B-1, but as the elevator built by the new method as poloskořepiny of corrugated aluminum sheet. It worked so much so that the same construction of the tail surfaces used all of the following dvouplošné fighter jets to Boeing. The chassis was also modified, the newly matched rather F2B-1 and between podvozkovými legs bore the strut bearing detent hooks (to the end of the 20. years on aircraft carriers used rope longitudinal, serving rather to protect against drifting than to capture), but soon released. Remained the possibility to swap the wheels for the float. In this form it was already the navy with the aircraft satisfied and ordered for 73 machines as F3B-1, buy also modified the prototype.
