Has anyone Re proped the G23?

[nyryan2001]

I'm going to run back to back tests with the 2 props.
I plan to record:
0-23mph w/ full OEM ballast (3 times per prop)
RPM @ 11.0mph
RPM @ 23.0mph
Top Speed (for those who care (I don't))

If anyone has any other measurements they want done let me know before Saturday.

Now, timing.... I timed mine 0-23...hammered down from a dead stop....and stopped the time as soon as I saw 23mph on the dash.... NO speed control for my measurements. Not as scientific... but faster runs

Another guy did his runs and used speed control set to 23, and stopped time when the speed control took over and beeped.

I didnt do that, as speed control backs it off some prior to 23....

I bet if you dont use speed control your 0-23 runs full OEM ballast will be right at 11-12 seconds... and your top speed unloaded right at 35-36.

I was already considering which I should do...with or without cruise. As you said, without cruise is faster. On the down side, its not realistic to how most of us pull a wakeboarder and that's the information we're really trying to attain. Obviously that's the whole point in choosing 23mph. Most of us don't race up to 23mph full throttle and then hand control the speed. One guy that rides with us actually does, he never uses cruise. But he also coaches professionally and spends many hundreds of hours driving a boat a year. Other than him, everyone I know uses cruise.

I'll do the top speed test with no ballast, just people and a full tank of gas. I'll also report the # of people we have on the boat for the test. I'll be running 87 octane in the 450 so my power will be down compared to someone that runs 91+. Thus my times may be slower than someone running 91+, or someone with less people or less gear/stereo than I have. But overall it should still be very representative of what to expect.

Ok well I ran mine tonight. It is way to much prop for my boat. We normally run 4-6 adults and kids. First the prop has a wired whine/sing at 1000-1200 rpm ( about 5 mph). I didn't have a chance to test times or any truly hard data. The boat had GREAT pick up out of the hole until 16 mph, then it vibrated the boat until 19.5 then stopped vibrsting. This was with full factory ballast. My wire said if you slowly got into it was much better but reduced the time to 22 mph. After we were done and I let out the water I tried a hole shot with it. It rocketed to 16 and then the boat acted like the prop was cavitating and the motor hit the rev limiter at 5600+ when I brought the throttle down it dug in and when on to 35 top speed at 5600.

The main reason I bought it was for when we had a boat load of people for partys and pulling a tube. I think the other prop 2315 will be a better fit for me. I think if the vibration was not so bad I would keep it, but I can't live with it.

[nyryan2001]

Wow, what a mess. Thx for the feedback, I wonder if V8 will have the same results.

2315 here. Zero vibration. Zero cavitation or hitting the rev limiter. There is sometimes a whine at 5mph like you described.

[V8 Killer]

Man...sure hope I don't share your results Texoma! I'll know in about 12 hours.

I just got back from a week in Eastern WA, I have the 2313 on my boat, we put over 30 hours on the boat during the week! I feel like it needs a lot of help on the prop. Most times just stock ballast and 3 people in the boat and wakeboarding double ups seemed to use huge amounts of gas! Wake surfing we started with 1100 extra in the bow, 1100 left locker and 600 in back right and rpms were under 3500 and the wake was huge. I feel re propping it would be better there though. ( we had to stop weighting the boat that way because anything over a 750 in the back locker will bend the panel in-between the engine compartment! I really hope I get some better performance out of a different prop. I am not sure which model to go to and am looking for more feedback.

I am ADDICTED to double ups!

That is some very impressive air. Looks like your having a blast!

Well, thanks to a missing prop puller in my toolbox at my office/shop, I don't have any 2419 results to share. I'll get them next Saturday (August 3rd) for everyone.
I'll post all my #'s next weekend side by side with the 2419 prop.

Has anyone noticed when you first put your G in (assuming you turn off your batteries after each use) that it takes a lot longer to get up to speed? It seems the ECU has to learn the weight and how to best deploy the NCRS and throttle/power. As the day goes on we can get on plane significantly quicker. The only difference between our first attempts of the day and our last attempts was 254lbs of fuel and 2 people weighing ~250 total = ~500 pounds.

The difference from 0-23 at the beginning vs. the end of day was TEN SECONDS.
Winds were not much of a factor all day, water was relatively smooth all day, etc. This isn't the first time, its just the first time I have actual numbers to back it up.

I changed to the 2419 and was able to use it over the weekend. Felt like a completely different boat, ran perfectly without any issues. 2 adults tanks full - no vibration or whining. Not that it matters but top speed made me curious - 38. I did not time to 23 but there was a significant difference and I am very pleased with the adjustment.

I'm surprised you got such good results Nauty220. I put it on my G23 450 this weekend and with a boat load of people I got the vibration issues from 16-20mph. With 10 adults (4 of them being on the large size) and full ballast, I could not get the boat on plane. I tried to pull back a little to ease the vibration and it didn't have enough to get on plane (even with moving people up front). I tried to push it a little harder and hit the rev limiter and it threw some engine codes for cylinder misfires. Yesterday, we went out with four people and empty tanks it was fine (but that also includes the extra wait for my stereo). I really liked how fast it got on plane with that little bit of weight, but with a heavily waited boat it didn't work well at all for me. I spoke with JT and he wants me to speak with Jim at ACME. I'm waiting on his call and will post the results of my conversation but I'm likely going to try a 2315 since nobody seems to have issues with that one right now.

[nyryan2001]

So thats 2/3 reporting issues using the 2419 on the 450 G23. We need V8 to chime in with feedback.

Nauty- did you try throwing the throttle down hard while sac'd out full ballast?

[Laketexoma]

We had a lake party yesterday and I had 12 people in the boat and pulled 4 on a tube. All adults. the 2419 did a lot better with all the weight. I still got the vibration but not a bad. I guess if you are massively over weighted it is fine. But for what we normally do the 2315 is a better choice. I don't think that the stock prop would have been able to even move that much weight. If it was not for the horrible vibration I would love this prop.

We surfed and wakeboarded. I used the throttle accordingly. Dont know if I "threw it down hard"

Spoke with Jim Thelen at ACME today and his gut feeling before ever telling my experience is the 2419 has too little of a cup for a heavily weighted boat. He said he thinks the prop is slipping and grabbing and that is why you get the vibration. That's why the 2419 works fine for a lightly weighted boat. He did say that one of his employees did say the 2419 should work on a G23, but Jim T. was a little cautious about it. He thinks the 2315 is about the best we can do on our boats right now. There is some talk of ACME designing a better prop in the future for our boats, but isn't sure if and when it will happen. I'm going to have my 2419 recupped to that of 2315. If that works, I have the two 2313s that I have recupped to that of a 2315. Apparently this is a relatively inexpensive adjustment for a cup change which can be done at most prop shops. I've spoken with ACME and Nettle Props about doing this, so this may be a good way to make use your existing prop.

"Jeff Carroll: The newer Nautiques have an extreme amount of ballast, and require lots of power to move through the water. Does Nautique have anything planned to address the always-growing power requirements of these heavier boats?

Greg Meloon: Jeff, that question is something on which we frequently focus. The G Series 409 and 450 engines have been coupled with a 2:1 v-drive for the 2014 model year. This change will allow us to use a 17x17 propeller to maximize performance."


I want a 17! I wonder if the 2013 G will be able to work with this? can you change the ratio?
