In Australia the use of recreational boats with outboard motors is high. In the State of Queensland alone there are 150,000 registered boats. The propeller wash of may cause increased sediment movement rates leading to resuspension of sediments impacting on the environment. This paper reports our measurements of the velocity field of the propeller of an outboard motor, and also present mathematical models established for estimation of the velocity fields induced by outboard motor propellers.
