A propeller driven surfing device includes an elongated body defining an
accommodation chamber for receiving a drive motor and a power supply
therein. A propeller is driven by the drive motor, and is disposed
outwardly and rearwardly of the elongated body. A shell member includes a
front surrounding segment which surrounds and which is spaced apart from
the elongated body to define a passageway therebetween, and a rear
surrounding segment which extends rearwardly to terminate at a distal end
that is disposed rearwardly of the propeller. The front surrounding
segment and the distal end respectively define a water intake port and a
water outlet port which are disposed upstream and downstream of the
passageway, respectively, such that water flows from the intake port and
out of the outlet port through the passageway.
