I just bought a 94 waveraider. Where is the cooling inlet? I don't have a manual and don't know how to flush it. I was just going to go down to the hardware store and see if they have a simple adapter with a garden hose screw on one side and a small pipe to plug into a cooling line on the other side, I don't need a fancy quick release kit.

What hose do I plug the garden hose into and where is it located on the ski?
