280 k-planes on a 24 outlaw
 

anyone ever installed them. want to see some pics. will be a good winter project.

I have 280s on my 27 Formula and I would say they are a little large. You breath on the tab switch and can just about roll the boat on its side. I would probably go with 150s if I were to do it again. Jeff Wurl

well, i got a good deal on them and i dont even have tabs at all. sooo i was wondering if anyone has installed them on a 24 outlaw and where they had them placed. i am running in the low 70s and on smooth watere she can chine hard. also planing can be a little tough sometimes. i will be taking the project on this winter. alsi i will be putting on external steering.

may be different boat and dana tabs but you can look mine over anytime.

BTW you going down to pool 26 Sept 11, for the races?

If your battery platforms go all the way to the transom, it will make it more of a challenge.

naah prob gonna stay put. and i will look yours over.. you gonna be out for labor day?

i have about 8 to 10 inches between the transom and those boxes. think ill be ok? and where can i get lines? and i have one extra trim pump and valve body. if i just get another can i use mercruiser trim pumps fopr k planes?

Iput them on my 24 back in 91 keep ripping off the bennett ones:party-smiley-004: and put 380s on with the shortie liked them the best:coolcowboy:, but took them off for the saber28 cause it has a box and konrad,

Will be work'n entire labor day weekend.
Currently boat is in shop and appearently they are unsure what is wrong with it and having Merc go over the scan.
I keep it in the valley so when I get it back we can meet up and you check them out.

This is my old boat. 95 24 outlaw with 454 mag at 485 hp. The boat did 70 on gps. I loved the kplanes and external steering. The kplanes were easy to install. I mounted the pumps on the transom.

I will be installing some on my 240 (same as 24 Outlaw) soon. Somebody along the way had them on it before a long time ago and thus one of the reason's for the transom rotting due to a shoddy hole repair.

I don't plan on mouting them as far out as FBRONCO, probably about 4 to 6 inches in from the chine, parallel to the hull bottom.

I think i may pick up some mph since it wont do the death chine. she walks hard! what kind of steering did u install? the add on or full. i think im just gonna run the add on single ram.

The external steering was an add-on type, not full hydraulic to the helm. It was from WPM. Worked great.

with the add on steering you still get walk, I did and just kept into it sawing the wheel back and forth the boat ran fine as long as I kept my rhythm up and I got to 83 running out of prop. my k planes are close to the chine I'll measure them.

I had a set of 380s on my 240 sport, before I bought the boat. They were removed before I bought the boat, and I have alot of chine right now, I have my outdrive raised 3 inches too. I am installing a set of the eddie marines this winter, the biggest set they make. I dont see a problem with going bigger. Just dont do the whole trip and stuff move when playing in the cruiser wakes...


Ill be up at the shootout on the 11th..any word on what boats are gunna be there??

if you want to get rid of chine walk full steering will do it or get it close, with the add on you still have a cable running up the dash:party-smiley-004:, I just practice sawing the wheel back and forth more on flat water but not so much needed in 2 plus at 80 plus.

what prop are you running?

I have 2. running a 1.50 bravo 1... 24p bravo 1 labbed by mercury racing. 55-5600rpms. (New Livorsi gauges) runs solid 70's best is 72 with the 4 blade. also have some bullchit labbed mirage plus 23 can run about 5400. think she is over cupped. but i have got 75 out of her.

I have been playing the prop game for awhile. i think my next attempt will be a stock mirege plus 23. my best rpm range will be in the 55-5700 rpm range.

does WPM still exist? im pricing sets right now... looking at my options.

cool, take your time though. im gonna tackle this bad boy over the winter.

mine is a 26b1 labbed, 5800 to 6000rpm 83.2 gps a 28b1 would of been higher speeds. prop shaft was raised 2'' with a shortiek planes were 280 then 380.

Off of my subject but i got some action potos from a buddys phone sunday!!!!!!

found this boat on ebay. it looks like it had k-planes. this a good spot for them?

ok here wt i got single hyr. steering 718 hp 136 drive rwith a 23mirage prop doing 80.6 mph at 5600rpm . still testing . chine walk none take your boat on plane set the drive then go full throttle.once top speed then ajust outdrive . try this and see if it help you out . good luck and one other thing when you put your trim tabs on? watch you dont put them to low i install longer ones . they were to low i trim my drive up the tabs held the boat from going up so i had to cut the down a little

yeah I keep forgetting to go measure ,I'll leave a note by my bed been working on the saber my baja is up for sale kinda.:coolcowboy:

Any interest in working a trade for a stock 23P Mirage Plus for the Bravo?

naah, i like the bravo. and its labbed.

Again, If you want to look mine over its just down the road.
Anytime!
I will be there tonight to put batts back in and the Wednesday to tow it to sterling.

Remember, if you're trying to tame or cure chine walk, dropping the tabs a bit will do that - but the extra drag will actually cost you a few MPH. Using the wheel to tame it will not cost you any speed, but you'd better have hydraulic steering to eliminate any slop. It will also dramatically reduce wear and tear on your steering and drive - not to mention making for a much safer ride.

Laster has a 24' Progression here (that I've driven) with 280 K-Planes on it and they work great. Mounted correctly, they will actually make your boat perform as if the hull were much longer. Mounted incorrectly, you'll loose speed.

Where you need to mount them (side to side) depends on how much of your hull (at the transom) is normally in the water. Mine are mounted over the first set of lifting strakes. If you look at pictures of my boat at speed below though, they're not even close to contatcting the water. (That's the way I wanted it.) The 22' Progression that was on the cover of Powerboat in 1992 had them mounted at the chines - and they proved basically useless. So, before you mount them, do some research!

thats my problem. I want to mount them once and only once. i have that pic above of the one that is a stripped hull. you can see their locations. and even above yet there is another peorons 24 that are located in a different place.

I had this thread in the baja section and speed girl was nice enough to move it for me. i was hoping that i could get a little more input of where they should be located for all around performance.

There are probably a number of locations that would work for your hull. The picture you posted shows them above the first set of lifting strakes - parallel to the planing bottom - and I'd bet that would work. Based on the 24' Bajas I've seen, I'd also bet that right out at the corners - above the outside chines - would work too. In fact I'd be really tempted to mount them there - and horizontally like Fountan now mounts them. Less drag with more control.

Probably the biggest hint I can give you is to mount them up about 1/4" on the transom from the planing bottom no matter where you mount them laterally. If you mount them too low, you'll loose speed whether they're up or down due to drag. Oh yea, and use lots of Life Caulk when you mount them too. Not sealing holes in a transom properly will ruin your boat in short order.

I looked at lots of pictures and talked to a number of folks who had mounted tabs on the same hull before selecting where I wanted to mount mine. I lost no speed and have all of the tab I need in any kind of water I'm silly enough to run in now.

Here is the the stock location of the Bennet tabs on my old '93 24 Outlaw. Outlawcowgirl now owns the boat and I'm pretty sure she now has 280 Kplanes on it.

I would mount them at least 1/2-3/4" above the bottom.

thanks, and you say horizontal... So just straight across but at the outside of the boat? seems like a cool idea.

Griff, How ya been? thanks for posting. and thank you for the pics! have you got any more pics of that outlaw? I see the pink (baja called it lipstick i think) around the transom. i think your old outlaw and mine may have had the same color scheme.

anyways, i was leaning tward mounting them like the stripped boat in the pic that you only see the whitness marks of having k planes. i want control. i am also talking to bob madera about a set of heads for my 509. hoping to make 600hp so i am trying to get my ducks in a row.

and to anyone else viewing this thread. i would be interested in k-plane switches, hydraulic lines , and circuitry. I can run my own circuits but if someone has the connections for the pump electrical and such i would also be interested in purchacing them.

Thank you to everyone so far, I am so glad to have all the replies. I just want to drill through the transom once ya know:lolhit:

Similar, but mine was only red black and gray.

Outlawcowgirl put a 525SC in it, added hyd steering, bigger tabs and lot more. She ran 79mph in the LOTO Shootout with a few years ago.

On a 24, the 280 tabs will be plenty even on the way outside. It won't take as much tab on a 24 OL as on a bigger boat. I had them on my 28 Pantera and have them on my 32 AT.
Here is a pic of them mounted on my 28 Pantera. Dropping them just a little makes a huge difference on both boats. They were mounted about 3/4" above the bottom and are the same on my 32 AT.

In between the red marks is about where I plan on putting mine.

If you don't have a swim platform, you could have somebody else drive and watch how the water breaks off the transom at speed, and see where the tabs would be most effective. Personally I want mine a little wider for running out on Erie when we have a funny wind.

Yes, Griff (as always) is correct in that you can mount your tabs even higher up the transom than I recommended. My recommendation was more of a minimum dimension. Don’t go any higher than he suggested though because you’ll start compromising the effectiveness of the tabs.

Remember one thing about K-Planes. The “fully retracted” angle is set at the factory by design. (So is the “fully down” position.) With most other tab designs, one can modify that angle through the placement of the upper cylinder mount relative to the actual tab hinge. Place the upper cylinder mount a bit further up the transom and your “fully up” position is further up – possibly lessening drag when you don’t need your tabs. (Again, where you mount them relative to the planning bottom affects this somewhat too.) On the flip side, when you do this, you also limit your “fully down” position, so be careful. I wanted to make sure mine were nowhere near the water when fully retracted, so my tabs are 3/8” up on the transom and the cylinders are a little farther up than the manufacturer recommended – but I’m perfectly happy.

As for mounted them parallel to the water, a number of manufacturers (Fountain being just one) now mount them this way. True, less of the tab actually comes in contact with the water at a given angle, but this also lessens drag. If I get a chance, I’ll try to snap a picture of the 33” Fountain we’ve got on the showroom floor with them mounted this way.

so, like c deezy modified in thaat pic... it seems like the pantera and the bennet setup had them riding/ending on that first notch in the bottom of the transom.

whats that notch called? the first chine?

It's actually the trailing edge of a Lifting Strake.

A notch in the transom is what Fountain (and others) use to help them raise the drive height (X-Dimension) to lessen drag. A notch is generally a short, cut out area right at the bottom of the transom / keel area in front of the drive.

The Chine is the area at the outer edges of the hull where the side of the hull and the planing bottom meet.

So, would the general consensus be that the inner edge of the k-planes should bmeet up with the lifting strake and be 3/4 of an inch from the bottom of the boat? would that be my best overall bet. good for planing, can lay one down if i got a couple fat chicks on one side and have them out of the way if im making a speed run?

that pic of the stripped boat has them over the lifting strake a little. not much but a couple inches. seems like that strake would make that portion of the tab not contact any water.
