5.3 L in a 2016 G23

[NautiqueJeff]

In surf mode, NCRS is configurable without turning the Auto/High setting off. I recommend leaving it set this way at all times.

[nyryan2001]

and just run NCRS 5 plowing water everywhere you go? Even when you aren't doing water sports?

throwng roughly twice the wake everywhere you go, wasting fuel and limiting visibility from now rise? Not everyone is 6'3".

i recommend absokutely not to. Crank the NCRS up when you need it.

As someone who "Gs" on a budget, pays full price for gas and boat, No tax write offs...,and trying to be courteous as possible to other boaters and property owners.

What is the PDM? I have felt that my H6 is pretty much identical to the ZR450 in my 2015 in both HP and fuel consumption. Am I speaking heresy here? I know that getting up on plane with 8 people and full ballast was not happening at one point in my last Lake powell trip (3600 feet elevation). There are times when I am sure that the NCRS does absolutely nothing, then times I think it does something. I drove around some with it both on Auto and then doing it manually and I am pretty sure that my manual NCRS does nothing at all. Before I come on here and go all ape crazy, I planned on playing with it on a flat water day so I can assess the wake as well as the
planing capacity.

Sorry about the hijack, but the point being that having an Auto NCRS that works is very helpful when your power is not quite sufficient.

I believe the PDM is a computer but not really sure

Can't you leave the NCRS on auto and still adjust in to zero when cruising? My dealer told me that NCRS auto should always be on.

What's your cruise speed? If you're on a busy lake like me... Likely 23-25 mph, you can't run 30+ across my lake unless you want to lose your fillings. NCRS at 5 still works at those 25mph speeds, requires 2-300 more Rpm than NCRS 0.

hey I'm all about if if folks want to deal with the bow rise, bigger wake and wasted fuel just getting across the lake.

i just don't want a Natique engineer to jump on here and read that and make it that way all the time.

i'd like the Nautique engineers to make Auto NCRS for surf speeds.

[NautiqueJeff]

NCRS at 5 means that the plate is fully-retracted, allowing the bow to come out of the water. Running NCRS at 0 is lifting the back of the boat, but pushing the bow down. That would certainly make the boat plow more than running NCRS at 5 at speed.

[Whitetail15]

nyryan, I would have to think at speeds 25 and up, the boat would be planed off, and to lower rpm and increase fuel usage, you would want as much hull out of the water as possible. That would be the 5 setting. That is were the plate goes in the "auto" position at those speeds. Have not checked the rpm on my boat at 25 mph with ncrs at 0 then at 5, but my guess is it will be less in the 5 setting as compared to the 0 setting that has the bow lower and more hull in the water.

maybe these boats are different, and getting the rear of boat out the water with bow lower is more efficient with rpm and fuel. Someone would have to check . If so , then the 0 setting would be better for cruising, and you could see better as well. I don't think that is the case though.

[nyryan2001]

guys go run your boats and verify. NCRS 5, plate retracted...is much less efficient, bow high, higher RPM at 5. Much bigger wake.

NCRS isn't a magic technology. It's a center trim tab that's all. Same as what's been used on planing boats for 50yrs.

the G hull is shaped so that without this NCRS plate extended, pushed down, the curved G hull runs bow high and throws a huge wake. NCRS 0 = extended, pushes the plate down = bow down and more efficient prop angle, less rpms, and smaller wake.

Cheers, enjoy.

[nyryan2001]

Also... Time a 0-25mph with full ballast launch with your auto NCRS at 5... And then do it again at NCRS 0. Roughly ~3+ seconds faster at 0 as your auto NCRS kicks in around 16mph and drags the hull.

also, launching on NCRS 0 until after 20+mph will allow you to carry another ~500lbs vs running auto NCRS 5.

i was running full 2850 ballast, + 8 adults, + another 2-3000in ballast. The big issue that allows a faster launch and carry more weight is the more efficient prop angle at NCRS 0. Cranking up to 5 after 20mph is fine. But if you hit the wall and get stuck at 15-18... Bring the NCRS back to 0 and watch what happens when carrying real heavy weights.

[Whitetail15]

another question

if you have ncrs auto to "off position" and you have it set to zero (the plate in down position) when you come to a stop and look under the boat, is it down? OR does it move to that zero position after a certain speed.

[DocPhil]

OK ok. No 5.3 liter

[nyryan2001]

No, NCRS zero = down = default position, bow down, smaller wake, more efficient. 5 is retracted, allows bow high.. Or cranked up perse, big wake.

I think Jeff has it 100% wrong. And I only want NCRS 5 when I'm wanting to throw big wakes.

food for thought.... If I were wrong... Why does auto NCRS at 5 go to zero under ~15mph? Cuz it's most efficient, allows a faster and easier launch with heavier weights.

[Beg4wake]

I thought that in NCRS Auto, the plate started in the 0 position when you launch and until you get up and on plane, then switches to the 5 position after up to speed.

[nyryan2001]

Beg, yes, that's correct.

[FunkyBunch]

Nyryan I agree with you and just yesterday saved a copy of back to dock with ncrs at 0. I almost immediately dropped a couple hundred rpm's.
