The drives should be low enough to try some of the merc aluminum 4 blades QA4 they should give more transom lift and come in the correct pitch ranges.

Call Lynn Darr at Marysville Propeller in Grandville Michigan....he'll have some idea of what to run and may even have some wheels to loan you to try out. He's a good guy....tell him Mike Ozinga sent you. I send him a bit of business from time to time.

I run one of his Powertech 4 blade props and they DO come in the pitche's you need. Mine holds the bow up or down really well. Better than a Bravo One.
