Adding bushings to steering deflector nozzle to increase precision (remove slop)

[Bruce]

@Scottintexas would you like to be the guinea pig for a 3d printed replacement?

Sure if it's something that you're interested in trying and is easy, if not I don't mind ordering, I'm in no rush,

I actually had looked at that site and saw CAD over on the right side and thought it was wanting Canadian dollars and wasn't going to entertain that

Looking to do the same on my 16, the bushings will run me around 40 bucks shipped from Pbc, if that’s my only option no biggie but Seems a bit steep considering I paid like 10 bucks when I did a couple years ago on my older boat. Any ideas?

@Philip, those bushings seem to have gone up. They were not a perfect fit but were the closest fit that I could find at the time. You might search for a similar product and find something better.

I took measurements for 3D printing a bushing and arrived at OD of steering arm 7.9mm, arm thickness 12.0mm, bolt OD 6.1mm, and the cable end had a gap of 13.2mm.

I tried to print a bushing but the 0.4mm nozzle currently on my printer is too wide to print the part. I have a 0.25mm nozzle on the way and will try it again. 3D printed bushings would not last as long as the brass ones have but should be smoother and a better fit.

Thanks Bruce. I just bought them. 40 bucks lol.

I need to test longevity but these provide greater precision and smoother operation than the metal bushings.

 

[Philip]

Bruce I’ll take a set. Still waiting on PBC to mail
Mine. Let me know how much. Thanks bud

So I was looking for replacements for mine today. Found this page on the McMaster catalog, just need to figure out which would be the right match McMaster-Carr

 

[Philip]

Bruce any info in these? My PCB ones came in but I distorted ones in vice.

@Scottintexas has a pair. I am hoping he will test them and let us know how they hold up. I have had one in for about a hundred miles, perhaps 4 hours of running. Seems to be holding up so far.

Got a part number and vendor in those plastic ones? I'll gladly pickup a set to test as well.

The vendor is @Bruce , he printed them. This is the one Scott was looking for earlier in the thread. It requires a little drilling out to fit. Bruce designed/made the plastic ones to fit without modifications. I too, could Beta test some bushings. Awaiting Feedback, before I buy aluminum/modify.

Thanks @zipper

Did Yamaha really drill these out to some oddball dimension, and not use some standard parts off the shelf? I haven't taken calipers to mine yet, but the sloppy steering has always been a complaint.

I'll try to take some time and get some dimensions tonight, and see what I can come up with.

 

[Philip]

I’ll replace every year lol. Let me know I’ll be another beta and gladly pay.

These things are cheap to print but expensive to ship.

How about $10 mailed for a four pack of bushings?

I can't guarantee how long they will last.......

 

[Philip]

@Bruce pm you. Sounds good

It would be interesting to compare your measurements to mine.

My measurements were
Fork Inner Diameter 7.9mm
Bolt Outer Diameter 6.1mm (must be a mistake)
Fork gap 13.2mm
Receiver thickness 12.0mm

The bushings that I printed are
Inner Diameter 5.8mm
Outer Diameter 7.7mm
Total Length 12.9
Flange Thickness 0.8mm

The drilled out metal bushings that I used had an OD of 7mm and ID of 6mm.

My note on the bolt measurement must have been wrong.

Six hours of printing and I have a fresh batch.
