G23 Prop Fell Off .....

[FEVB]

I would think twice buying a G with all these casualties out there with no clear solution

Heard tonight that Nautique is working on a fix for the shaft....but in the meantime, this is a temporary fix to catch the prop. Currently it is only available for the 450 "Horse" motor.......

I would guess they discussed it at length and believe they are better off both reputation, sales and financially to just fix them as they go and not speak to it publicly, and not recall, or put out a service bulletin...

Unfortunately they are probably right on all 3 counts...ethically probably not...

Agree 100%.
They did put out a service bulletin in 2015, but there has not been any updated one since.

I'm willing to bet you're 100% right. My guess is they used the formula Ed Norton used in the movie Fight Club dealing with auto recalls.

That’s actually not a bad idea.

1st let me say I am a new G23 owner. I have just under 50 hours on the boat and couldn't be happier with the performance. I am chiming in about the shaft issue as my friend is the one who posted the last pictures of a broken shaft this past Saturday. I took the boat to the dealer yesterday and found out today that their other location has indeed seen several others break since the updated shafts were installed. They are obviously going to repair under warranty for me. Definitely not what I expected to see happen back when I was purchasing the boat in May. It is disheartening for this type of issue on a new boat, but I still think these boats are superior.

"no easy solution" = = no cheap solution. I bet there is a easy solution.

[greggmck]

There is an easy solution. But it's not cheap. The primary cause for these shaft failures is from the asymmetric prop loading causing the shaft to fail at the keyway. The keyway is machined (cut) into the shaft weaking it at the load point of the prop hub. The solution would be to switch to a splined shaft and prop. If Nautique increase the ballast for the G23 in 2020 they will almost certainly have to change to a 1 1/2 shaft. It would make most sense to also switch to a splined shaft / prop combination at that time.

That shouldn’t need to be the solution Greg... look at centurion, Tige, Malibu, you name it.... nobody else is having this problem.

I have 5k in ballast with a 1 1/8 shaft still intact, the logic isn’t there.....

No way to quantify, but this has to be resulting in lost sales. If this issue was happening Prostars, I would've purchased a 200 without blinking.

[greggmck]

If you look at ALL the factors affecting prop shaft loading you will see that there are only TWO boats with 17" or larger props AND a 2:1 transmission, with a significant frequency of surfing. The 2018 ProStar with an 18" prop and 2:1 transmission and the G23 with the 17. The ProStar uses a splined shaft. The G23 a keyway. And after speaking to engineers working on this very problem this is what they are thinking.
