    Default Pump Setup On Daytona

    I Had Some Friends Take A Few Pics Of My Boat Running And Looks Really Wet. What Shoe Setup Are Most Of You Guys Running? I Know That Every boat Is Different, But Wheres A Good Place To Start? Back Cut? Also Im Runing A Wedge 2* Upside Down. Does That Normally Help With Lift? Its Got A Shoe Right Now And The Ride Plate Is Pretty High Not Sure What Degree.

    The Hull Feels Like It Gets Pretty Light With A Good Head Wind But Thats The Only Time. But Looks Like Its Breaking Water Just Behind The Front Seats On The Sponsons. Ill Post Pics Asap

    Its Got The Rounded Keel.

    Not Looking To Race Just Wondering If Theres A Good Starting Point/Setup That Would Help Without Too Much Trouble.

    This Is The Only Pic I Have On My Work Computer. I Have Some Better Ones At Home With Just Me In The Boat. This One Probably Isnt Much Help. The Ass End Just Looks Really Heavy In All The Pics.

    Looks like it needs more HP I'm sure someone with a 19 can give you a good starting point. do you have any suction pressure ports?

    It Never Has Enough HP! No Suction Pressure Ports.

    put the skinny side of the wedge up top and take the ride plate down to about 2 degrees up from zero should be a good place to start. My boat had the fat side up and was really wet just behind the seats turned it around and put the 2 degrees in the ride plate and what a big difference.

    Putting the skinny side of the wedge up will push the bow down, It raises the thrust level. By running the wedge fat side up will lower the thrust line pushing the bow up. You'll want to run the bottom pin of the droop about 3/4" above the ride plate. 2 to 2.5 degrees up is a good starting point for daytonas.

    Is he running a place diverter?

    If so, I agree run the thrust line as mentioned but make sure you get your 4 degrees back or removed depending on what direction you flip that wedge. If your running a fixed nozzle you need to be tuning the ride with nozzle angle rather than thrust height and worry about thrust height later (fine tuning) providing the droop your running puts you in a workable range of thrust line height.

    WOT, rather than just talking wedges, the correct thing to do is to get a digital protractor and talk actual nozzle angles and rideplate angles in relation to the bottom of boat. if your ready to get into it we can tell you how to get these measurements. Also what intake is in the boat? Any work to the bottom? What style shoe and depth in relation to keel? Loader? Pics?

    A typical 19 daytona race setup starting point would be 1-2 degrees down on the nozzle and 2 up on the plate, yours will probably want positive nozzle angle but I could be wrong. They are all different. Im seeing more and more guys get away with positive nozzle angle these days in fast fast boats but bottoms are being done different now.

    Great thread.
    Yes, lets get into the specifics with the digital protractor, etc. This info could be used to check my boat out as well. While I know my boat needs more HP, it also rides super wet. I am sure there are already threads that cover the measurements, i'm too lazy to search.
    WOT lives pretty close to me. Maybe we need to set up a pump measurement/inspection/comparison day for our two Daytonas.

    Probably not, wouldnt hurt to go over how to measure all the dimensions so people have an idea of how to check this stuff.

    A long time ago I printed out something off of Real Jet Boats, it was a cool little write up on how to measure this stuff and it was done off the Biz. Remeber that? I think Jim Lee did it?

    Would be cool to see that come back up. Maybe MikeF has it saved?

    yes he is running a place diverter. berk 4 degree intake, set back pump, hand hole outside the boat. probably a 650 to 700 lb bare hull

    Funny, I was just looking for it and at it after your post.......whoa.

    It would be kinda hard to post it up w/ the photos attached in the proper positions.

    Let me see.
