Unless that boat is filled with helium and made of cardboard, I just don't see 36hp at 8 knots as being realistic. As said by others, likely closer to 4gph. The 2gph figure would be a for an economical cruise speed of 6.5 to 7 knots.
For a boat that size with the limited access to the under-sole engine space (it's not really an engine"room"), the single is great. Even if the bow thruster is undersized you should still be okay with some warping skills in heavier winds. The single will have a larger rudder than twins and the only modification you may wish to make would be to add a fishtail wedge to it for better maneuverability.
