Still messing with this boat....have added all new gauges, a 250efi with a 23 pitch laser prop. It's a 25 inch shaft, chine walks like crazy and can't get much more than 65 out of it at 5800rpm. Get slots of looks and thumbs ups etc, runs great in the ocean, but was expecting to see 75 mph...tried a 26 pitch trophy plus 4 blade, but couldn't pull the rpms, thinking about a 25 pitch fury and 20in mid. Boat has nice kiekafer tabs...need help, anyone!?

Still trying to figure this boat out.....a 250xs pushed it to 80, my 250 efi can barely do 65....and chine walks like crazy!

You have to get a 20 inch mid section for starters(a offshore mid is better,single piston). You should have a low water pick up. Put on a 4 or 5 inch jack plate. Run the boat and jack the motor up till you start loosing water pressure then drop it back down a little. I have one with 2-2.5 off shores, these boats are a handful to drive. But with the right set up and enough seat time they are the badest small boats out there. Try a cleaver prop, they work well on these boats.

this boat did 64mph with that old yamaha, 20" mid,hydraulic jack plate and needed trim . no chime walk, your dragging your 25" motor

It does sound like the motor may be too low. Have you measured the height of the propshaft in relation to the bottom of the pad?
