Some wild ideas, some not!

A replaceable gel cell battery that I can buy from you when it won't hold a charge anymore. One that isn't way overpriced either. It bugs me when I'm going to buy batteries for a drill and they cost as much as a new drill with 2 batteries, a recharger, and a case. I end up selling the old drill and buying a new one. Seems like a waste to me. It's even worse when I can't change the battery as is done with many shavers.

If the pump is mounted by the front bulkhead it would be nice to have a switch that can be turned on and off by foot control. I won't have to open my spray skirt to turn it on/off.

Small tabs to allow it to be attached with fasteners. Some of the holes in the tabs could be slotted to a bigger hole so that if one fastener was removed and the others loosened the box could easily be removed with the remaining fasteners still installed. Or better yet, some sort of a quick release mechanism such as using a wall or floor mounting plate.

Mounting plates sold separately so I can easily move it from kayak to kayak.

Have the pump and battery case combined and make it so I can attach an inlet hose to the pump and the other end of the hose could be slipped onto a floor mounted fitting that allows it to sit in the bottom of the water. In other words I may not want to try to find a place on the floor to mount it, or it may not easily fit in the bottom of the V of the floor. Maybe the best spot is mounted on the front bulkhead off of the floor with a suction hose going down to the floor. Advantages of this idea are that I wont have to use up valuable space behind my seat for the pump, the pump won't be in the way of my feet as the toes are farther apart than the heels, the pump is at toe height to easily turn off and on.

A way to plug it into one of those solar recharge pads bungied under the deck bungies (OK, now I'm getting out of control).

Check valve.

Many builders here don't have lathes. You could have a local woodworker turn outlets made of wood that are long enough to epoxy in from the inside and cut off the excess on the outside after it's installed. We can round off the outlet, seal it with epoxy and whatever else needs to be done to install it. These could be sold as a separate item and could be available in a variety of woods (Pine, Ash, Western Red Cedar, Walnut, Redwood, etc..)

Thanks for considering some of these ideas.
