Hi Guys.

I hope you can help me.

I have much to much slip in my props. Last season i ran with 26 inch Mirage, but i couldn't get any speed out of it. 61 mph with 5000 rpm. This season i then tried a Revolution 4 25 inch, but with almost the same result 62 mph with 5000 rpm.
it feels like it sucks air down to the prop and just makes white foam behind the boat..

Have anyone of you had the same problem as i?

What do you guys think the problem is?

The , drive is in mint condition it is a Bravo X 1,5 withe a imco nosecone.

im no expert but if you can remove the nose cone I think you would see better results. My understanding is the cones only help above 70 ish

Yes, but it is the same without the nosecone... I have tried it ..

Rev Limiter set at 5000RPM? if it turns 5000 see if you can borrow a different prop, remember apples to apples , from what I have read and seen Brands Act different, even if same pitch,,,, document every run ,, Fuel Level, Number of Passengers, Water conditions (slight chop/flat glass) Air Temp, Engine running the same each time,,,
I know Prop Shaft Height makes a BIG DIFFERENCE

Thanks guys...

i have a small diameter 26 4 blade "labbed" and I'm running just under 65 with a 502 mag… if you have an actually 500hp in it then you have more than just prop issues.
