I bought a 4 blade Stainless prop on ebay it just arrived. It was advertised as a Mercur Bravo 1 4 blade. It is not. I am unaware of the manufacturer and very disapointed in my purchase. THE Part Number of the PROP IS HC-CL24R O-IV. Does anyone know the manufacturer? Please Help

Are you sure its not a Q-IV at the end?? If so its a Hydromotive.

Looks like a RH 24 pitch Hyrodromotive Q-IV prop to me.

Yep, Hydromotive. The part# on my 26 Hydro is HC-CL26R Q-IV.

If it's in good shape, thay are great props. What kind of boat do you have? Some boats like the Hydromotive props and some don't.

Thanks for the info on my prop. THe boat I am going to try it on is a 28' Sleekcraft approx 5,000 pounds, The engine is 454 full roller 9.3 comp 10 hours new,approx 500HP but may be lacking because of the EMI exhaust.I tried a 26 bravo 1 and the rpm was only at 4800, I can push the motor to 5600 RPM max. Any info would be helpfull.
Thanks

I believe it is a 1.51 Ratio drive. I paid about $300 for the prop it looks like new.

I( believe I definently saw 65MPH but the max on my gps was 73. I am not sure if the max was correct. possibly it turned on in my truck. This weekend I will get a chance to test it out.

I tried the Hydromotive prop this weekend. Here are the results.
Approx 90 gallons of fuel 110 degree weather 4 people. The RPMS were at approx 5K the boat topped out onGPS at 63.
I felt the boat had more bottow end with the 26 bravo but less rpm and more speed 65. I think the bravo 1 24 will work the best. Anyone want to trade a like new 24 P hydro for a bravo 1 24 p.
