My steering has developed this twitch when on plane. I turn the wheel and it has some resistance to turning the wheel and then all of sudden it gets really easy then back again to the resistance. Watching youtube vids it says to shake the engine while on the trailer and if it wobbles you have air in the system. I did that and it showed a small amount of side to side movement. I was expecting a lot more. While on trailer I moved the steering wheel and there seems to be a lot of play in the turning before anything happens at the motor. I don't know if I have that same play while in the water and motor running. Researching the bleeding of the system it shows a bleeder port in front of the steering where you hook a bottle of fluid to. I could not find this fitting. It must be behind the dash. I have a tilt steering wheel installed so I assume the fitting I am looking for must be hidden. Any advice would be appreciated. Got a St Claire trip coming next Sat and would like to have this resolved by then.
