Default 28 Regulator prop selection, stern lift

I used to run a 26 Reg with twin F300s. All of these boats like stern lift. That boat ran great with Rev 4s with 200 HPDIs but terrible with Rev 4s with the 300s. Today with the 28 with 21P SWS2 props with full fuel could only reach 5600 RPMs trimmed to 8 bars and we need more stern lift. I was thinking Eco Enertias in 18P, Rev 4s in 20P, or OFS4s in 19P. Any thoughts?

Hydrofoils will get the job done. A lot cheaper than testing and finding the optimum propellers.

Some will come along and state that hydrofoils are not worth a damn. But finding and using a propeller that might do the same thing is a wonderful thing.

There are also trim tabs as a solution.

If the boat is in need of stern lift is it possible that the Cg needs to be moved forward?

The COG is fine. Every Regulator I have run is ass heavy. Just want to get the bow down at 3000-3800 RPM without having to use trim tabs (which work very well but burn a lot of fuel). The boat needs to come out of the hole faster. I have used hydrofoils on small flats boats with 50-90 HP engines and they can truly work wonders despite how ugly they are. However, I dont want to put them on a twin engine CC
