If you are passing destructive tests OK....But....Could use more flow and fusion at the edges ....Ripples could be closer together.....I would use 5356 because The lift goes in the water...4043 turns gray and dull after exposure to water ... especially ocean water...I'm being highly critical here but that is what you get when you post a picture like that......Easy for me to pass judgement while I sit at the computer..I'm retired ......Good Luck
