The Mercury 525 motor needs to run at 5350-5400 RPM at WOT to achieve max top end. You need 450-500 RPM actually to do so. I would recommend that you try some different props before labbing. Maybe quest can post his Bravo performance numbers as well as his Hering numbers, to help you out.

Can you PM or email me your best price on a Mercury Labbed 30P for my XR.
Thanks

The cost for a Lab Finsihed Bravo I is $989.99 which includes the XR hub kit. I do think however that you should try to getr some feedback on semi-cleavers on your boat. I was hoping quest would post his data from his Hering Props.

Chad1,
We are getting ready to make an announcement about our props next week.. We have implemented a new treatment which makes the props very STRONG! Stay tuned.

The herring vs bravo test I did is really not relivant to the single engine 26 ft cat of blueamerican because my current boat is a 31 ft twin engine AO. But here is the test results. all runs were made in 72 deg weather on relative smooth water. The boat ran out of hp at 5700 RPM with the 34 pitched labbed bravos but since 32 pitch 5 blade herrings were more efficient, they required less HP at all rpm levels and therefore I was able to turn the motors to 6000 rpm when I hit the rev limiter. The herrings look very similar to the bravos but have, one extra blade and are razor sharp.

Ps I tried another manufacturers 5 blade on my 26 ft AO. It was not labbed. The boat ran higher mph at each rpm level but I lost top speed( motor wouldnt turn over 5500 RPM) because it put too much load on the motor.
I cannot get the attachment graph to post

Can you post a photo of the Hering props? I have had positive results with 5B props on twin engines as well, but the singles have been challenging with 5B props.
