Works just as advertised, the soft rubber cups seal perfectly and provide great water flow for my Pro CS. Just put tape on the lower water pick up so that water doesn’t shoot out. Merc sells a goofy kit for $80 but duct tape works better.

I like this style the best for running my Mercury to test things out before hitting the water. Fits tight, hose hooks right up and feeds the motor plenty of water. Doesn't slip off like the other styles.
