Scottb7 even though we disagree on every post on Planet Nautique, this is the perfect opportunity to post you driving your G 21 with the trolling motor in motion after the prop sheer

Oh yeah, post a video of the trolling motor on the G21. That would be hilarious to see. Less hilarious if it was due to the prop falling off.

Since I was putting boat away for the season, I thought about this thread.

Here is a pic of my shaft. Key way goes all the way to strut bearing. This shaft was placed at 175 hours after original shaft broke on former owner. Boat with this shaft now has about 550 hours. Hard to say if I am on borrowed time or not. We almost never surf, but I don't know if that has much to do with those that break.

I was told there is a new service bulliten to replace some boats with certain drive shafts. Has anyone had theirs replaced as a precaution?

Mine was going to be replaced as a precaution G23 2017 but it literally broke the next week after the dealer told me this. My neighbor who had a 2015 G23 , had his replaced as a precaution by the same dealer one week after mine broke . So to answer your question they have begun to replace as precautions vs waiting for the shafts to fail

It has almost been a year without an update to this thread. I saw today what I think is a first for me...another brand with a shaft failure. 2017 Tige. Just tubing around the middle of the lake when it broke off.

I made a new post and have since been directed here. I'll add to this thread in case there's a need to continue tracking this issue. Sorry to pick the scab on what may be a healing wound...

2018 G23 H6

Bent prop shaft in July of 2018, less than 50 hours

Bent prop shaft in July of 2021, 187 hours

In both instances, we were cruising at 25 mph, ballasts empty, across moderately rough water at least 100 feet deep. In both occurrences, I felt a slight shudder that began to intensify and I immediately cut power. I guess I should feel fortunate that I was able to throttle back before the shaft sheared, so at least I was able to limp back to the dock.

After dropping the boat off at the dealer in 2018 I was told the bent shaft was a "known issue", which I assumed meant that the "known issue" had been addressed and was no longer a concern. I see now that really meant "we know about the problem and will replace a defective shaft with another defective shaft. Fingers crossed!".

That may be an unfair characterization, but I do take my boat in for service every 50 hours (usually sooner); a visual inspection of the shaft would take 30 seconds (after reading through this thread for a few days I know that the tell-tale sign of the defective shafts is that the keyway is cut all the way to the shaft strut). I'm particularly bothered as to how or why the replacement shaft, which was also defective, wasn't later replaced with a non-defective shaft once it was available. Seems like basic preventative maintenance to me and PR preservation.

Definitely, it’s frustrating to experience a failure when my family has invested a lot of effort to travel away from home base. Twice. Yes, it’s frustrating that a "known issue" in 2018 is still affecting my ability to use my boat in 2021.

I'm guessing that this is no longer a problem due to the lack of new posts to this thread? But I’m due to take delivery of a 2022 G23 in early August and I’m trying to find some reassurance that this "known issue" is now a "non-issue". I'm also here to ask for a reality check (if needed) as to what my expectations of my dealer should be regarding their handling of this affair, meaning is it realistic of me to presume the dealer would be on the look out for a defective item, especially one that they installed, and preemptively replace it during the course of servicing my boat?

My prop shaft at the point where the bend occurred, and the exposed keyway.

and this is only on G boats? Have we seen it across any other Nautique models?

[NautiqueJeff]

This was only an issue on the G-series boats.

[scottb7]

Wasn't 2019 the last year they fell off? or was it 2018 models?

[greggmck]

My understanding is 2018 was the last year that had the bad shafts.

Update for those that may be concerned about the shaft on their G:

From my dealer: "Good news on the shaft it had a hairline crack so that is [a] warranty [replacement]. Nautique has changed the "Cause" to torque specs basically, so this shaft we just put in should be good." (I'm not sure what that last bit means)

Fingers crossed!

As a precaution, my recommendation would be to ask your dealer to insect your shaft (get your minds out of the gutter) for defects when you have your G in for service.

I think that you need to go buy a lottery ticket, right now. You bent two shafts, but didn't have the prop fall off either time, that is very unusual. It is more unusual since at least one of the boats was well beyond the supposed fix. As noted, this thread basically died when they finally did find the fix.

I think I've used all my luck up for a while, so the lottery ticket would be money thrown away.

The dealer did tell me that the shaft was cracked (and not merely bent) when I dropped off the boat, so you are correct, I did get very lucky.

Of note, I took the boat out this weekend with the new shaft and she ran considerably smoother than in recent outings. I had in my head that the shaft went from good to bad in a nanosecond, while it appears that it was a slow burn.
