Got a 2:1 gearbox in your G? I did some prop testing on an alternative....

[Tallredrider]

Called Delta Prop today and they recommended the Acme 3081 for my 2017 G23 with H6 - 450 . This prop is an 18" with a 17.5 pitch....... hmmm..... interesting.

Cool. Please let us know how it works. Do it for the team

At my 2700 feet, I am not sure that with 6-8 people, full ballast, I can handle much more prop than the stock 17 X 17 if I want to wakeboard. I have the H6. If I could sell my 17 X 16.5 to someone who needs to be a wakemonster with a bunch of extra ballast, I would do it. I have it for my spare prop, it has never been mounted, still in the box.

For surfing, I am confident that I can handle a lot more weight, and rip right up to surf speeds.

Well..... got an email from Delta Props and it said that after having a conversation with Acme, the two of them have changed their recommendations and now say that the Acme 3087 would be best for the G23-H6.... it's a 17.5 x 17.5


Would sure like to hear from someone with some time with one of these

[SierraWave]

I have the 550. I'll get data next month on the 17.5x19.5

If you have the 550hp with the 2:1.....don't even think about any other prop. Get an ACME 3081. It's is absolutely awesome. I went from 3850rpm surfing with full stock ballast and 7 people in the boat, plus gear, and a full tank of gas down to 3050rpm at 11.4mph. It is awesome! Did A LOT of talking to Delta Props and ACME prop engineers and bought it 2 weeks ago. Last weekend out with it on, it blew my mind. Wake boarding at 23mph full stock ballast, rpm was 3200rpm.....I'm in FL, so no altitude here, but results will follow the same kind of rpm drops wherever you are. If you need persuading, the next time you're out, go run your boat at 3800-3900rpm and really listen to the motor(nothing wrong with running it there,it's just screaming) then go pull throttle back to 3000rpm....ahhhhhh, I hear myself saving gas money and truly think my engine will last longer. That 550 has a TON of power and in no way is "lugging" as some people have expressed concern about. Bottom Line - ACME 3081

[Tallredrider]

The 3081 is an 18 X 17.5, in case anybody was wondering.

Anyone run the 17.5 X 17.5 on the H6 yet?

Interesting, you try either one yet?

This^. My boat is not quite two months old (I have the H6 450) Aside form the huge difference in slow speed maneuvering (which I mastered easily enough) the biggest difference in this boat and my last boat (a Cobalt duo-prop stern drive) is the crazy RPMs needed to cruise at a slow speed. Yes, I know the engine can handle it, but it drives me stark raving crazy. I find many passengers will ask me "can you go any faster?" when I'm just cruising down the river at 18-20MPH with no ballast, because of course, most people do cruise a little faster then that. I just hate the sound of that engine screaming. Hate it.

My buddy ended up putting the same prop I used (3047) on his 2014 G23 with a 409....... He absolutely loves it, and hasn't had any issue getting up to speed wakeboarding. He can't tell the difference between the props, except the drastic reduction in noise, using almost half as much fuel, and able to cruise a bit faster.

For what it's worth- Now that I have 80+ hours on the 3047, I can better compare the fuel mileage difference vs the stock 17x17 I had on the G for 120ish hours of use last summer. Using the average from this year so far (92 hours total, with about 80 hours on the 3047), I have burned 456 gallons of fuel according to my fuel pump counter. That's about 4.95 gal/hour. Last year I averaged almost 8gph. That's a pretty huge difference.

Sounds like Hyperlitecowboy has another awesome alternative. I'll be honest, I avoided that prop only because of the bigger diameter, and the added stress on the shaft, with Gs already having some issues with that. Who knows, probably doesn't make a difference, but that was my reasoning with picking the 3047.

Hyperlite- Any change in top cruising speed? I'm guessing with the pitch being 17.5, it's probably about the same as the stock unloaded cruising speed? And then it really shines while towing with the reduced prop slip from the larger diameter?

I want to know this as well: I want to know the RPM drop...

[Tallredrider]

The 3047 is the 17 X 19, to save anyone the googling. I do much better with direct description of the prop, not the prop number.

With a full crew of 8-10 people and stock ballast, I am a little slow to get on plane a little with full ballast and the stock 17 X 17. I worry the 17 X 19 would make that worse, but it might not. I am almost at 3000 feet. I haven't tried any new props yet.

I'm hesitant to make that switch on my H6 also...even though I'm at sea level. I rarely do any "cruising" in my boat, and I'm just not sure that much more pitch is going to get the boat moving as fast as I want it to. Would love to give it a try though...if I could find a company that would give me my money back if I don't like it.

I did a lot of prop testing this season and ended up with the ACME 3081. My data will give you an idea however how pitch will impact your performance. When I went with a 19 pitch it just killed acceleration with a 2/1 tranny and 550 motor, at altitude. I cruise at 25 mph very comfortably now without the feel that my motor is "rapped out." Here's my data if it's helpful:

....according to my fuel pump counter. ...

What is a fuel pump counter?

I'm also interested to hear more about your friend with a 409. Amount of ballast, type of use (e.g. wakeboarding vs. surfing vs. cruising), typical speed pulling riders, etc. I have a '15 with a 409...we wakeboard almost entirely with stock plus a few hundred pounds.

I have my own fuel tank and pump at my dock. Makes it easy to keep a total of fuel used.

He usually wakeboards with just stock ballast and a few people onboard. Not sure if he has tried adding much extra ballast for wakeboarding. He does add a bunch of weight for surfing and has no issue.


lakepowellman- where do you have the 2 750s added? In the rear compartments?

[RDT-G23]

I really want to know the RPM results with the above referenced prop. I don't generally have a full boat while surfing, (probably not more than 5 in the boat with a surfer behind it)-so I'm not at all worried about hole-shot. (I am at 824' MSL) I like to cruise in the evenings up the river, no ballast, and not usually more than 4-6 folks in the boat. I want the RPMs DOWN in this case. I also pull kids on tubes... The 17.5 X 17.5 may be just the ticket-if the RPM reduction is significant enough to spend ~$800...
