This underwater walljump is very long. Some jump assistance, cross room jump, or a flatley jump from the door frame is needed to get to the first overhang. The cross room jump requires an adjacent runway of 3 tiles (with no open end) with HiJump disabled. Perform a turnaround just before hitting the ceiling.

Do a low spin jump and press against the right side of the door frame. Wall jump as low as possible, jumping as soon as possible after moving away from the wall. Immediately turn back to the right and try to press against the door frame again before the transition, while maintaining spin.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. This uses exactly 14 tiles (with no open end) - more rises too fast to do the trick, less does not have the height needed to reach the door. Use angle to break spin, then a momentumConservingTurnaround as early as possible, right as you pass the above tile horizontally. Using the background for positioning may help. The second momentumConservingTurnaround is as late as possible, just before touching the above platform. A third momentumConservingTurnaround is used on the door as it is opening.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it to the top. It helps to enter as low as possible and with as much horizontal speed as possible and with HiJump turned off.
