Waterbox 35.2 DC return pump suggestions

Jonny Walker · Jan 7, 2021

So I bought the water box AIO 35.2
but I am having trouble trying to find a good DC return pump. The return pump chamber for this model is 5.5”x4.7”x17.7
Any suggestions?

Innovative Marine Mighty Jet DC Pump will fit nicely, is absolutely silent, and it's rated at 326 GPH. Includes a display where you can set flow from 174-326GPH. Costs $89.

Lol the waterbox stock pumps are so loud. The mighjet is the way to go

I am using a Sicce Syncra 0.5 and its perfect. You really dont want more than 200gph otherwise you'll have way too much flow through the rear overflows.

I have the MightyJet 528 running in mine, you will like it.

It's dead silent.

How about the Sicce Syncra SDC 3.0? I've got the IM 528 mighty jet and it fits even with the intake screen. What ya all think, will it fit?

The problem I'm having is one, brand new it wouldn't start and tossed an error on the controller. I had to actually disassemble the pump and use some Molykote grease just to get it to start. Now that was 2 months ago. I lubed it up and stowed it away till my WB showed up last week and wouldn't you know the pump tried twice to spin up and finally it ran. Now the issue is my center sump chamber constantly rises and drops constantly as if the pump isn't able to remain a constant. It triggers my ATO. I've even removed the socks and all filter media and it still does it. So that's why I'm considering going with the Sicce syncra SDC 3.0

I'm pretty sure it'll fit but I'm going to be sure I can return it if it doesn't.
