Limiting streamlines on blades of a highly skewed controllable pitch propeller (HSCPP) model (MP.NO. 94-1) are visualized by the oil film method over wide operating conditions including reverse pitch angle. Experiments are carried out at the circulating water channel. Observations were done at advance ratio J=0.0, =0.4, 0.6 and 0.8 at design pitch angle (θ=0 degree), and J=-0.2, 0.0, 0.2 and 0.4 at near zero pitch angle (θ=-20 degree) and full reverse pitch angle (θ=-40 degree). The Model propeller diameter is 250 mm, and Reynold's number was around 4.6×10<SUP>5</SUP> to 6.1×10<SUP>5</SUP>. No serious stall nor turbulent separation was observed in the experiments. Therefore, it can be concluded that for HSCPP the boundary layer assumption is approved as well for conventional CPP even at off-design conditions.
