DonZi 26

hi guys i am new to this site !!
i have a 1999 donzi 26zx with a 502 carb 415hp...my question is what prop am i gonna go for ????
rumour has it that these hulls need 4 bladed props to hook well...i have tried a mirage plus 25p 3 blade prop R/H however top rpm was 4600 and top speed at wot was 64mph on gps. Guys keep in mind that the 502 max rpm would be somwere between the lines of 5000-5200rpm so the engine with this prop was not giving its outmost!
The other prop i have tested was a L/H hydromotive quad4 24p 4 bladed which maxed out at 4900rpm but top speed at wot was around 60mph on gps....this looks very weird to me as i managed to gain 300rpm over the mirage however lost 4mph...as regards to trim angles the boat was trimmed just about the same with both prop tests....
When speaking to the factory they told me that this model came out with a bravo1 24p 4blade prop and the boat could reach speeds of up to 70mph on gps (not sure about this)
I am looking for overall good performance, however i would like a prop that gives me the max top end from the boat and good stability.
i am confused as i dont want to throw money down the drain and buy props which ar useless...
Can anyone help me please ?? any info would be greatly appreciated!
thanks
