Questions
Are "Kiekhaefer Aero Marine" pumps any different?
How do you fill Kiekhaefer Aero Marine pumps
Do you think the valving and performance is the same for the pumps?

I had two Kaama on mine for the drives and two Kiekhaefer for the tabs. Like the two you have in your picture at 9 O'clock. Not sure on performance with the ones you have, but had a K pump fail and replaced with one that was given to me that was rigged for a hatch and the rate of actuation speed was like doubly fast, it had the smaller motor on top too. Good luck with your project.

I replaced both trim pumps on mine with regular ol' Merc units because of a leaking valve plate. Trim up, creep down.

In the process, I learned there are 2 types of Merc trim pumps. High pressure and High volume. High pressure is slower. High volume is faster.
It's been so long now, I don't remember specifics, but I remember I had to track down the high volumes through several part number changes to get the ones I wanted.
