Help with skimmer pump replacement

[IPWitan]

I have a AquaMaxx ConeS CO-1 in-sump skimmer. The pump is a Shark 1.5, modified Sicce 2.0 Syncra. I need a new pump and impeller. I think the old one got stuck, heated up, and caused the inside chamber of the pump to crack in two places.The pump is currently out of stock at MarineDepot. I cannot find it in stock anywhere, except 1 website I don't know and it is listed for 60 bucks more than the others. I have sent MarineDepot and 1/2 dozen others ian email asking if they have the pump or can recommend an alternative. As of yet, no one responded.

So do I need the exact same one? According to AquaMaxx, the pump generate 475 g/h and is rated for 90 to 175. I have a 75 gallon tank, so I may not need quite as much power as the original. There are several others out there such as a PSK-600 for an ASM ($116). This pump is rated at 600 g/p.

Aquacave sells a Sicce sk200 for $90. This pump is rated at 350 g/h, so less than my current one. They also sell the psk600 for $119. Links to everything below

Summary -

1 - do I need the same pump
2 - can I get something that is less powerful or should I go up?
3 - pump sits under skimmer, so I am concerned that a bigger pump may cause a problem.

Which pump does your skimmer use?
Dimensions of the pump might be more of a concern than the output since it sits under your skimmer.

Shark 1.5, modified Sicce 2.0 Syncra. A link is above. I am thinking of going with a Sicce SK 200. It is smaller than my existing one, but I don't think that is actually an issue. the skimmer is rated for more than my tank can handle. As for the size, it actually sits on an egg crate stand. I could cut out a spot for the pump if it is too big. as for the size, I don't actually know. That sort of info is hard to find.

Also, MarineDepot is indeed out of stock with new ones coming in July.

Fair enough, but there are other similar pumps for 70 less. With that price, I could just get a brand new skimmer. One of the legs broke - but can be fixed - so getting a new one is not a total loss. I guess I am wondering if there is a problem going with an Sicce SK 200 for under 80ish, or the more powerful Sicce psk 600 for 115ish
