    Launch Control Seacock

    Can anyone tell me where the seacock valve for the launch control system is located on a '99 Sport?

    If you mean the ball valve that opens up the thru-hull, there aren't any on a 99 Sport (at least not factory). If you mean a 99 Air, it is in the front of the engine box compartment slightly on the port side.

    If you mean the 2 knobs that open up the vent lines so that water can come in and out of the ballast tanks (based on pressure), they are under the throttle pad, slightly behind where the throttle is located.

    If it's an after market system, it could be anywhere. I put mine near the rudder linkage in the wayback under a piece of removable floor.

      The seacock values I assume your talking about are under my engine in my 2001 Pro Air. If you lift the engine box and look under there should be 2 pipes with blue handles on them to open and close. Again thats just where they are on my 01 Pro Air, so I very well could be wrong.
