IMHO, there is no way on gods green earth you will pick up 10-15 MPH with an impeller change.. maybe 2MPH if your pump was worn out....

Also, 75 MPH at what RPM? among dozens of other questions I'm sure...:)bulb

IMHO I don't think the cost is worth 2 mph. 75 seems to be respectable to me. But then I'm not really racing any one.

Im sure I will be corrected if wrong but some hulls are not made to go that fast. You can have a 800hp motor in a whatever lets say Tahiti and it wont go 80mph before it throws you sideways out of the boat. You can always go to stainless impeller, keel, loader, ride plate, place diverter or obviously more horse power.

It is possible to gain ten mph for sure. Dialed in system vs bone stock and variables galore. Say a guy has a boat with a AA impeller with an engine with low torque and changes to a B impeller.

Hondo Man , 550 hp puts you over the "magic mark" for safe use of Aluminum Impellers (both OEM and after market) IMO so your looking at a Bronze or Stainless 500 to 900 range , re your goal , as said above 75 mph is very respectable for that hull and that HP, much more will take some fairly significant Horse power increase . Call if we can help Tom

absolutely. gps's all read 10 mph fast in canada due to global warming. :)hand

dunno about 85, but 550 hp absorbed should easily exceed 75 if the setup is right. 750??? 750 would push my 23' hallet over 80...

We'll see in a couple weeks here :)sphss

I think 76Bonneville's change in impeller, from 4700rpm (A) 72mph, then went to 5800rpm (c) at 81mph.... maybe he'll chime in
