New props needed for 28ft Donzi ZX w/ Twin 350s

[stationinc]

2001 28ft Donzi ZX w/ Twin 350s
Top speed now @ approx 57 to 63 @ approx 4000 "depending on conditions"
Like to get more speed as everyone !!!!!!!

Have damaged 23s (not sure if I can repair)
Was thinking of going w/ 4 bladed props
Need advise for additional speed & out of the hole ??

Any help will be appreciated

Thanks

That speed is low by nearly 10 MPH. Have your props always been damaged since you have had the boat? You should be spinning the 23's to a good 4800 RPM near 70MPH.

How many hours on it? where is your trim set?

I put a prop thread on Offshoreonly for 28ZX's in the Donzi section (I did it there instead of here because it seems more ZX guys are on that site). There are lots of options but it seems on the 350 / 1.5 drive ratio the best is the 23 Mirage +.

Good props and more trim.

Thanks for the reply
I will try more trim on both old ones & also the new ones if I go that route

The Mirage + doesn't like a lot of trim on this hull.
