2016 g23 gph

[DocPhil]

So I now have a sample size of 2 fillups and I am averaging 3.6 GPH in a 2016 G23!!

Is this possible?!? Am I making an error somewhere? That seems incredibly low.

This is about 50% surfing fully ballasted, 20% cruising at around 4200 RPM/30 mph, 20% wakeboarding, 5% other watersports, 5% WOT runs.

That does seem incredibly low. Wakeboard boats are heavy or can be heavy and their hull isn't very efficient. If the hull was efficient, it wouldn't produce a good wake. It would be like a bass boat.

I talked with a few of my buddies that have 2014 and newer Bus and they have averaged anywhere from high 3s to around 5.

I'm wondering if the combination of 2:1 tranny, prop size and DI motor if it is possible.

Anyone else measuring GPH in 2016 G. I know Jeff said he did. What numbers are you getting Jeff? Are my calculations possible?

I don't know how you can do this but we were averaging 13 GPH while surfing in a 2015 G23. 6-8 persons on board.

Whoa. That's excessive. I'd be looking for gas leaks. :-)

I know NY Ryan running like 5000+ ballast in his G was around 10-11 I think. BICBW

That's all subjective....
It depends on many minutes you are actually running in an hour. We are doing 30-45 minutes surfing each rider.

Well of course. That's why you look at average over time

It will vary from person to person of course. My question is whether 3.6 is possible running stock ballast as I described above

I don't believe it is possible. Maybe if you are crashing a lot and take your time getting back to the rider. Me and my people think surfing is just sitting there and gently going up and down the wave endlessly. So I think we crash less than people who actually do tricks. My RPM with the H6 is 3500 with stock ballast and a couple of folks in the boat.

I have not run numbers, but may be able to get some today from just 1 session. I am going to guess with stock ballast, I am more like 7-8 GPH.

On my 2016 G23 after approximately 100hrs. I used 536 gallons of gas

Okay so you are at 5.36 GPH. That is not too far off. What activities do you do and with what weight in ballast and people?

[Tallredrider]

Today I ran the numbers for you. It is just 1 trip and only 1.5 hours. But I filled up at the same gas station before and after, at the very same pump, so boat was exactly the same level.

I got 7.2 GPH. But that was just over 1.5 hours. But that jives with what I have experienced for the other 97 hours I have on the boat. Today we were surfing with no ballast for part of that time for my 12 year old lightweight daughter. So my usage is definitely more like 8 by the time we use full ballast all the time and a few more people.

2016 G23, H6 motor at 2700 feet elevation. Could elevation make quite a bit of difference?

This season has been my easiest to calculate, because I have my own fuel tank and pump in my boat house (sort of boat house. It's on shore, with a rail system, which is how I can legally have my own fuel tank)

As of this morning, my pump gauge is reading 532 gallons. My boat has 122 hours, of which 23 were from last fall. 99 hours on 532 gallons of fuel. That's an average of about 5.4gph. I feel like I hardly ever just cruise, or idle around in my boat. I am always either boarding or surfing. However, I bet the cruising and idling around adds up way more than I think because I burn way more than the average while surfing.

On 2 occasions I filled before I went out, and filled when I returned just to know my GPH while surfing. Both times were with full ballast, additional 600lbs under lounge seats, and 8-10 people in the boat. And both times I burned 9-10gph.

Mainly, I was trying to figure out if I should get higher pitched prop, to get my RPMs down while surfing. With the LSA and 2:1, a 17x17 is a bit overkill. A 17x18 would be nice IMO, but acme doesn't make one with the right cup. I should ask them if they would...... I tried an OJ 17x18, but it washed out my starboard wave for some reason.

These boats come under prop'd to allow you to bring 4-5000lbs up to 23mph. To do that you've gotta go low on pitch to allow you to hit 3000rpms as soon as you throw the throttle down.

if you don't need to bring crazy weights up to 23, or only surf, or only moderate weights to 23, you can add pitch to bring rpms down and save gas. Bringing super heavy weights over 14-17mph is very very hard.

running a higher pitched 16x15.5, I get 5-7gph heavy 4-5000lbs surfing and 8-11gph average for everything else.

I was able to get out on labor day and decided to do another careful measurement. This time close to 4 hours to judge it by. Mostly surfing, about 10% of the time with no ballast for the kiddie again. This time threw about 15% some tubing into the mix. I got 6.1 GPH with H6, 2016 G23, stock ballast only.

My guess is that tubing without ballast is easier on the gas consumption than surfing with full ballast, despite the frequent turns and harder accellerations.
