Volvo 280 DP props for trade

[sailinphelan]

I have two C6 stainless steel Volvo duo-props in great shape. I need some lower pitch props for a big slow boat with a Volvo 280dp, like a C1,2 or 3.
I have it on a houseboat and really like the dual prop, it handles great, almost like a thruster. Let me know if anybody has any props, aluminum is ok too.

I have a diesel on the 280 and it is geared for gas, so it turns real slow, I can't figure out what I actually need for it, but this one has a lot of slip, I think it is slipping a lot more than it is holding. It seems as the props get more pitch, they can't bite the water anymore at low boat speeds, it is a weird balance, and I haven't found it yet.
