I replaced the motor on my power, Tilton trim and pump assembly. Remove the cylinders to make sure there was no water in them reinstalled everything and it works great until I’m under Load and then it doesn’t go up unless I stop then I can raise it and then take off. I’ve been told it’s due to air in the system. I’ve been running it up and down to bleed it, but it still doesn’t resolve the issue. Should I bleed the cylinders? Also, any help would be appreciated.
