It is best to remove the lower unit from the engine to locate the water accumulation chamber which will either be in front or behind the water pump housing, depending on your motor.

Drill a 23/32 inch hole and tap a ½ inch pipe into the side of the lower unit that is coming into the chamber.

You will need to acquire a hose of appropriate length, (long enough to reach from the tapped hole, over the mounting bracket of the engine, and down to the pick up tube), Approximately 50-70 inches long with a #12 female fitting on one end and a ½ inch male pipe on the other.

Note: You must also close off the original factory installed water pick-up.

Mount the pick-up to the left-hand side of the pad or transom when using a right-hand rotating prop and vice versa for a left-hand rotating prop.

Mount the pick-up bracket as close to the bottom of the transom as possible. This will allow area for up and down adjustment of the pick-up tube, if required.

Note: The same instructions apply to both models of BMS International’s transom mounted water pick-up tubes.
