With the water damage "always on" it's doing slightly less than max Prime Punch damage, but also pushing 2 additional tiles and making water. It also removes something I considered a feature and part of their theme: using water to indirectly damage enemies who normally aren't affected by it.
That's actually a good point: comparing it to the Rift Walker's punch. Though you can balance that with the number of cores the upgrade requires. Like, if you replaced propeller with an ability that grants damage even if the target isn't above water, you could increase the cost of that ability to 3 cores from 2.
Though, you also mention wanting to keep the focus on use of water, so an alternative might be "+2 damage to all targeted tiles," so now the middle deals 5 damage to targets above water, 2 damage to targets not above water, and 2 damage to the side tiles.
