I've got a 46 bow, and yes... 2x MaxiJet 900s would most likely give you good flow assuming you set them up appropriately, as cmor commented. I started out with 2x MaxiJet 900s in addition to the output from a couple HOB
filters. In my opinion, my particular configuration was too much so I backed things off to 2x MaxiJet 600s. I switched gears after the Koralias got over their initial "issues" and I'm now using a single Koralia 2, along with the output from my HOB
filters, and things seem to be OK.
Instead of 2x MaxiJet 900s, I'd maybe suggest 2x Koralia 2 units. The flow rating on the Koralias are deceptive because the output is so much more dispersed than the MaxiJets. In terms of water velocity (not flow), I'd equate the Koralia 2 to a MaxiJet 900. The Koralias have a much nice flow pattern, although the MaxiJets are inexpensive and pretty much indestructible.
