Looking good Jon!

This was an issue that some of us who participated in the group buy a couple of years ago had. We ended up ordering slightly longer bolts for those locations.

Do you recall the exact bolt and size you acquired to replace?  I wouldn't mind getting them in advance so I can do the project as soon as my hugger is in.

Yep, I ordered em from Ron Ayers and here's the part numbers and size.

BOLT,SOCKET,10X67  Kaw # 92153-1944  Ayers part number 1100677

I bought some extra nuts at the time as well. (cuz I boogered up the originals)

NUT  Kaw # 92210-1139  Ayers part number 1107363

How man of each are required?  2?  And I'm confused... I looked the part on Ronayres.com and they look like OEM parts from Concours... if the OEM part is too short, what am I missing?  Or is it that one side is too short?

92153A 92153-1943 BOLT,SOCKET,10X63    
92153B 92153-1944 BOLT,SOCKET,10X67    
   

I see the part you reference is the 92153B which appears to be 4 mm longer than the other side... so the 67 is good for both sides and I'd just need one?

Someone mention my name?

I see what you did there

Are you comfortable with the softer stainless bolts in what may be a critical location?

I have some pics on my work PC, I'll show you what I'm talking about later today. If I remember.

Taff, stainless has it's place. I tend to err on the side of caution, especially when being wrong might mean being dead. I'm not an engineer or metallurgist so I don't know when 'good enough' might not be good enough. Others might disagree but to each his own. 

[Conrad]

Conrad, any help for me and other folks deciding to do this mod would be helpful.
More opinions and knowledge, better outcome as far as I am concerned.

Jon.

Here's the pics of my install using the stock bolts.

As you can see using the stock bolts the nuts just barely get the last bit of threads on the bolts and it would probably be fine for anyone less anal than I am. If you use the part numbers that I posted earlier the 67mm bolts are just a tad longer and the nuts get all of the threads. Using a longer bolt than 67mm will work of course but there's no need.

We mount 400lb+ + outboard motors on jack plates sometimes 12 in. back , making 370hp with four SS 1/2 bolts and I never heard of one snapping.

UPS has my rear hugger.....  should be on my doorstep when I get home!

On a side note - We need to talk!!  I blew up my outboard and am in need of another..  Now of any decent deals on a Merc 225 EFI or DFI?  or I would take a 200 powerhead only if price is right...

Send me a PM...  thx

Back on topic I was seriously considering a Carbon Fiber hugger to match my Muzzy Dual Carbon Exhaust but just can't bring myself to spend more money at this time...  Spent to much over past couple months not to mention my other love aka boat needs some attention

[Necron99]

LEFT TURN CLYDE!  lol

[Necron99]

So there's a step that was missed in the other guy's instructions, Taff was lucky enough to not have to remove his exhaust.   You'll see in my write out of this step how you can avoid it.

Install the stock exhaust.  Spend 15 minutes trying to figure out why the heck the mid pipe bolt won't go all the way through the hole.  Go inside and check the diagram on the shop manual.  Realizes that the back bracket goes INSIDE, not OUTSIDE.  Reinstall and the mid pipe bolt goes right through.

So...it only took me an hour or so (plus the extra enjoyment from the above step) to get 'er installed this a.m. before work.  Wanted to get it installed before bike night with my drinking buddies.  Large res available here - the file names without the "s": http://home.armourarchive.org/members/morgan/connie/hugger

Looks GREAT looking forward to getting one also .
