Default Props for a 2800 SCR with twin 4.3 V6

Anyone know what the proper props should be and pitch and any recommendations on where to go to purchase them.

the real question is how fast can you go?

32 mph at 4200 rpm..... at slack time.

i have the single 7.4, and the performance is identical.

I have a few boats with the 4.3, carburetor, bravo I or II
