I'm looking for propeller options for my boat. I have the original

28" x 28 pitch 3 blade NIBRAL Michigan Wheel props.

our engines are very similar as I have the 12V71TI engines with 850 hp. How did you (or the former owner) decide on those props?

What are you getting for speed at wide open throttle? I don't think I have seen more than 24 knots:-(

Sorry I cannot help with your soot question ... I have not noticed a problem in that regard.
