G23 Prop Fell Off .....

[SoCal G-Man]

Nautique dealer in SLC (where boat was purchased) is Croft Marine - there's no Nautique dealer at Lake Powell, so it was the Mastercraft dealer who did the shaft/prop replacement.

Good to know. Thanks!

I'm more interested in the loose coupler. As I have mentioned on other threads, ours was moments from catastrophic failure - all but two bolts were gone and the two remaining were mostly separated. The shaft was flopping around on the transmission. Same year boat - 2016 G23.

Did you notice if they used bolts that were too short? Ours were not even long enough to extend out pat the end of the unlock nuts, so no wonder they came undone.

For those still counting...yesterday had the same issue on our 2014 G21, driving about 22 mph across the lake, didn’t hit anything, no ballast at the time only 2 people in the boat. Have 90 hours on the boat, 409 engine. Other than that great boat..

It would be great if you could rotate the prop shaft to get a picture of the key way. Every shaft failure I have seen has the key way cut extended nearly to the strut. The "new" shafts have a shorter key way that is completely covered by the prop hub and well short of the strut reducing the weakness caused by the key way cut.

On a side note...after hearing the same excuses for years about a 'new manufacturer' solving the problem, it is awesome to not see any 2019 boats in this thread yet.

Excellent point! Hopefully, we never see that.

Here’s a picture of other side of shaft. Everything was replaced by Nautique under warranty.

My G23 2017 with 378 hours just scrummed to shaft break while surfing today. Another one bites the dust.

If I remember you posted a pic of your shaft months ago and it was one with the longer keyway. That still is the common denominator.

Yep glad we were at the end of the season and I was 1000 ft from my dock when the shaft broke

No better way to have a shaft failure!

Impressed,

I have always wondered how to tow a G if my shaft broke and nobody else is in the water. Was it hard? Did you have to be two people pulling while swimming?

Lol....I keep two paddles in my G. I've been passing them from old boat to new since 2000. I've only used them once. Throttle was a HAIR out of gear and boat wouldn't start. Paddled that tank one cove away back to the dock at night. Really funny when I figured it out.

2 paddles or a trolling motor a must have!
