Building Barefoot 196

[coosafooter]

Hey guys I plan on re powering my current 2007 196 with a new 6.0L, the 5.7 that is in the boat now has 350 hours on it now and is is perfect condition. If someone is interested in this engine it can be purchased for 5900.00.

Might I make a suggestion. We foot my 196 with 5.7 (run 43.5 with 2 in boat is a 220# behind) at 100 feet. I'm sure you foot your boat and know the wake isn't great at any line length.

I suggest taking the 5900.00 you are going to put into a new motor and buy a barefoot boat. We picked up a 92 flightcraft for 8K about 3 years ago. Inboard. At 70 feet it is awesome. We also ski a 94 Malibu Echlon with a 454 which will run 54 with 4 in the boat and 2 footers. My flighty will run 44 with 3 in the boat and 220 footer. You will get a much better wake.

I back slalom at 47-48 mph,the 196 with a Acme 15 pitch 3 blade is running 47 with just my wife driving and me in tow (225lbs). Which is fine but when we add one more person to the boat the speed drops to 46. If I add a barefoot plate it will drop it another 2mph. I feel that I add another 80 horsepower it will solve the top end problem. If the motor or boat doesnt sell soon it will be replaced with a new Sanger DXII.

That won't do it. It is not a shortage of available horsepower. At WOT and max RPM, your engine is producing a relatively low amount of horsepower.

An improvement would be another 1500 rpm or a much higher pitched prop that will get your engine down in the sweet spot where it does have some power. That 6.0L would help with RPM.

I've posted before...a desire for a two speed tranny.

Problem is...that boat is just not designed to go that fast.

I'm with Crad, get a barefoot boat. I thought it as well when the thread popped up but wasn't going to say it. I won't tell you what I'm shopping for but its not a DXII.

There are several incorrect statements that also conflict with each other here.

1. At WOT (max RPM), the engine should be very close to operating at its peak hp. The Excal makes peak power right around 5000 RPM.

2. Trying to spin the engine 1500rpm higher (~6500 RPM) would yield aweful top end (it is too far past the engine's hp peak) AND decrease its reliability.

3. Going to a higher pitch prop would LOWER (not raise) the WOT RPM's and would also negatively impact the top end, as well as hurt holeshot.

The goal is to prop the boat such that achieves a WOT RPM that is as close as possible to where it makes its peak hp. Correct Craft historically has done a pretty good job at this on their ski boats. Modern wakeboats are propped more for holeshot and their max RPM's are capped by a rev limiter, but thats another discussion altogether.

The 6.0L will in fact improve top end significantly. The 46-47mph that the Excal boat is capable now is very strong... are those numbers GPS? Im assuming that the hydrogate is up (trick/jump) as my father's former 196 (TSC2) was only good for 45 or so with no footer behind it. We havent tried to see how fast his new 196/409hp will pull a footer, but Id bet that its 50+, as its good for 53mph any given day, and has seen excursions up to 57mph with some weight in the back and ideal water conditions.

As far as a wake plate goes, I think you will have a very hard time finding something that will work on a 196 hull... it is not a flat bottom boat, especially in keel. You would be better off trying different positions of the hydrogate. Im not sure how much effect a plate would have on the wake other than changing the running attitude of the hull (bow down), which is what the gate does.

I think that trying to get $5900 for that Used Excal is going to be a very tough sell...

Yes I am using my new perfect pass for speed, Acme built the prop just for barefooting. I understand fuel injected motors and there is no way possible to get any more RPM. The 6.0 is the way to go, just trying to sell the engine that I have. I also have been playing around with a narrow plate the width of our keel. I just feel like adding 80 horsepower should increase the speed 7-8 mph.

Is that a DBW motor?

What comes with the motor for that price?

[coosafooter]

Yes DBW, fuel injected. It will be a bobtail. Which would be without the transmission.

Which version of Perfectpass? I assume Stargazer (GPS) should be accurate, but the paddlewheel based version is badly skewed once above slalom speeds. Ive seen 4-5mph variances.

I dont doubt that there is a way to tune that Excal to get a few more ponies, but that sort of project is probably not for the faint of heart.

I would be interested in seeing the plate that youre using, as well as pictures of the wake for comparison. Im not sure how it would affect the wake other than how it adjusts the boat's attitude (running angle), which the hydrogate already does. I assume youre installing it on the narrow part of the keel, at the level of the hull (hydrogate up- trick/jump)?

80 extra hp will not buy you 7-8mph... more like 5mph. The consensus seems to be that the 409hp 6.0L will generally push a 196 to 52-53mph with the gate up (unloaded).

Which prop did Acme recommend for barefooting on the Excal/196?

[Mikeski]

I considered repowering my 211 with a custom built 400+ cube motor. I advertised my 330EX here and other places. I had zero reasonable offers. I have now have a second boat...

The prop is 12.5 dia. X 15 pitch w/.150 cup 3 blade. I am using the star gazer no paddle wheel. The plate has been trashed, no change in wake shape, same wake produced using hydra gate.

Sounds like an Acme 2068, which is basically a 470 with extra cup (.150 vs. .105). My dad ran a 470 with .130 cup on his excal 196 (TSC2, no gate) and it was incrementally faster than the 422 (1/4-1/2 mph), so that makes sense. Id be interested to see how the 1442 ran as well- the TSC2+ hull has the room to run the larger diameter prop (13.25) and it should cut down on the revs a touch vs. a regular 470 without the extra (inefficient) cup.

I cant say Im surprised that the plate didnt help you... the hydrogate does a great job of adjusting the running attitude of the hull.

[coosafooter]

I spoke to Acme today we discussed going to the larger 13.25 diameter they explained that the larger diameter may hold the speed better than the 12.5 diameter.

[coosafooter]

Just a note, need at least 1'' clearence between prop and hull.

[TRBenj]

Just a note, need at least 1'' clearence between prop and hull.

Thats a good rule of thumb (Ive actually heard 10% of the prop's diameter) but you can violate that *a little* without doing damage. The stock prop on our '79 Barefoot Nautique was <1/2" away from the hull and it caused damage. I wouldnt sweat something on the range of 3/4" though. Just keep an eye on the hull to make sure no damage starts to form.

Going from memory, I think the TSC2/3 196 should have clearance for the 1442 (13.25" diameter) prop. Measure your clearance now and see if you can tolerate losing 3/8".
