Piranha props

[razbarb]

Would anyone know anything about the piranha modular composite propellers?
I'm looking at my options with the DT25.
The current "porridge" prop ( thanks bergalia) measures 9 1/2 x 9 1/2.
Would a 10 1/4 x 13 push the boat up out of the water quicker, but lower the top speed?
Thanks.

i've played around with but you have to be in clean water any debree and your replacing a blade
if your running a 9.5-9.5 and go to a 10.25-13 your hole shot and top end with both be hurt the engine has to get up to its max rpm range ?what engine and do you have room to put a 10.25 prop under your cav plate
