I am curious what you guys are running for X-dimmension on 28' ( or so ) single engine Straight V bottoms ( no pads , steps , or notches )

Please specify the boat , Weight , Cabin or no cabin , What drive , Prop , extension box or not , ect.........

What are you guys running ? & what kind prop slip #'s , if you don't know the slip#'s give the rpm , prop pitch & GPS ( only )speed

Thanks , Scott

The standard X for a single engine 28 Pantera without a notch is 17"--thats what Jo told me.

The propslip varies depending on power and prop used between about 12% and 18%

Yeah I know that Jo likes to run their non notched 28's about 5 - 5 1/4 below the V.

I am asking this obvoisly for my 28 Saber. Which as far as comparison it would probably be very similar to the setup on a 28 Pantera ( no notch transom ) & generally Jo sets them up with Bravo 4 blades.
The boat should come in around 5000# & will probably end up with a Konrad on it. I am just woundering with all of the new 5 & 6 bladers that are out now , am I best staying conservitive with the X & running a 4 blade bravo or going just a touch higer & running a 5 or 6 blade ?
Keep in mind the boat is a pleasure boat with a cabin & is a non step V that will need bow lift. Just trying to get some opinions to kick around at the moment.

Also, if I can help with the purchase, I'd like to be your distributor of choice.

Thanks Kirk, Where did your X end up at ? I would assume somewhere around 4 1/2 - 5 Due to the fact that you are running a box.

I would stay with the propshaft 4.5 to 5 inches below the bottom. I have a notch and was about 3.5" below the bottom before I added a bigger spacer. Lowering it an inch helped a lot in lifting the bow and prop slip went down.
