Hey guys. I am almost finished my build and i took my ski out today. It cavitates really really bad at low speeds. SO bad i can barely get up to speed to get it to stop. I realized im missing the seal between the pump and the body. Im assuming thats whats causing all this right? Im leaving for vaca with it tomorrow to go to maryland. If anyone is from maryland near chesepeake bay and has a spare one PLEASE LET ME KNOW!!! I need one bad. Im on a house right next to the bay bridge.
