Im Looking For A Set Of New Props!currently Im Running Mirage 3 Blade 25 On My 1998 38 Scarab Powered By 525sc's,I Do Have Smaller Pulleys And Am Running Superchillers And 1.5 Gear Ratio!mid 70s At Wide Open Throttle!whats The Next Pitch I Should Try And How Many Blades?Would A 25 Four Blade Be Better For More Top Or Maybe 26/27??My Set Up Should Get Me 80 With The Right Prop But What Would That Right Prop Be?

I was hitting 5800 with a set of 25 P Mirages. Switched to 26 four blade Bravo1's and turned 55-5600. That's all I've got for ya....but should get you started. Call Throttle Up, they will help you out!!

What gears do you have?

With 1.36 you have 15% slip and with 1.5 you would have 6% which is unlikely. With the 525's you need to run at 5380 at WOT. So you need to drop down in pitch or perform some prop adjustments, such as labbing , pitch change and cup adjustment to increase your RPM.

I Have 1.5 Gears,when Starting Off To Get On Plain,the Props Brake Loose Fairly Easily And I Have To Back Off The Throttles,cruise Is Good But It Does Take Some Time To Get Max Speed And When Trimmed I Do Have Quite A Roost!my Props Now Are 25mirage Plus 3 Blade,just Seems Like I Need More Bit!now With My New Set Up(pulleys And Chillers)im Wondering What Will Happen!

I can only give advice based on experience. I have a '91 Top Gun with Hawk 525's. Came with labbed 27 Mirage plus 3 blades. I had the same problem coming on plane. I switched to a 26 pitch 4 blade as I need more bite for flying ocean swells. I need to lab mine as I can only spin 5100 RPM. If you would like to try the the labbed 27's, let me know.

JJones,

I am re-reading this thread and I am not seeing your WOT RPM...Maybe I calculated your slip wrong. What is your WOT RPM? I think I got it off of the thread you deleted.

I am afraid to say that 6% is to good to be true with 3B props but if indeed this is true I WOULD NOT TOUCH those props...golden. So that being said I would verify all of your data. I would also encourage you to try some 4B props. They will carry your boat much better than the 3B props.
