Merc four blade 34's for best top MPH and Hering six blade 30's (15.25) for best overall prop.

what are the topends for each, and how much does the mid improve with the hering??????

Merc 34's ( labbed I believe) are good for 92-93 MPH ish. The Hering 6 blades will get the boat to 90-91 MPH. Phil once tested a boat with Hering 5 blades that saw 95 MPH on one particular boat. The Herings cruise just a little bit faster at the same rpm, but the boat handles noticeably better and jumps right onto plane like a ski boat. The 6 blades are incredibly silky smooth! I had 15.5 diameter 6 blade Herings, but went down to 15.25 6 blade Herings. Dropping down the diameter gave me even more bite when getting on plane and slightly better acceleration, while keeping the bow a little higher. The boat runs, drives and handles awesome with these props. I feel that these are the best overall prop for this boat.

thanks PM203....whats the RPM and MPH differences between the two in the midrange????

I was told alot, but in fact, it was a very minor increase with the 6 blades. The 6 blades excel in getting on plane, acceleration, handling amd smoothness. There is no comparison.

Herings are the way to go. I even tried the 5 blade maximus. Awesome cruise speed, but the way the boat handled was scary to say the least.
