Moto Massage Question For H/s Gurus!

Recommended Posts

I concur with a lot of these posts.  Hot Springs and the local dealer do not do part replacements rather they want to provide entire assemblies. In my first case, I had a leak in an end of the spa heater.  The local dealer wanted to replace the heater at a cost of $800.  I found an end cap replacement kit for $20 - did the replacement and save $780.  With regard to the moto massage hoses.  I found the same situation.  Hot Springs and the local dealer wanted to replace the moto massage assemblies and not the hoses themselves.  The moto massage assemblies come over $100 and with labor would be nearly $300-$350 dollars.  I am going to TRY to find the hoses and replace them myself.  I am wondering if there are any updates on DIY moto massage hoses???

Just did this repair and working like a charm.  $7 and a one week wait sure beats $100+ for a whole new assembly.  Have enough to replace it again if needed. Used 12x16 mm tubing and only problem is using the original clamps to hold it on.  Couple extra small zip ties on it for now.  Will be looking for something like a fuel line compression clamp in the future.  Specifically one that will hold up to the water and chemicals.

Just did the mod as my HS silicon tubing has wasted away/split on my DX motomassager on my 2006 Jetsetter and works a treat. Both arms zoom up and down as they should now for £7.49 from Amazon.


seems good quality silicon tube. If it lasts a year and needs replacing again took all of 30 mins to replace, so way cheaper than £134.00 for a new MM Vertebrae assembly.

How were you able to get the original hose off of both internal ends of the assembly? I have a 2016 Grandee and while one end pulls away easily, the other end (that screws into the tub) seems to be locked together.


Thanks -

Hi, I am currently on a trip, and I'm not able to view a MM spine. It's been over a year since I replaced mine, but going by memory...

I remember that one (or both ) ends have a collar that slides over the outside of the hose, locking it on the end fitting? Ij that's the case, just take a large screwdriver and pry it back. I do remember the original blue tubing can get stuck on the ends from time, but again, nothing that some serious (and careful) prying won't remove. remember, the old hosing will no longer be used, so if you damage it in removal, it's not a problem.

Hope this helps, let me know if you have any success. I will be home next week and can view the actual part, if needed.

Glad to know that my MM fix has been helping other HS owners!

OK, so whomever the original poster on this is, if you ever find yourself in the Baltimore area, let me know. I have a beer or five for you.

I was able to get the jets apart. The blue tubing on the inside pretty much just ripped away. I think years of the chemicals have just eaten through the rubber.

Once I pulled the one end off, I pushed the threaded end back a good inch or two. I was able to use a pair of needle nose pliers to pull the hose out through the threaded end opening.

I made it a point to keep all of the hose components. One post on here said the length of the hose you should cut is 9 inches. When I measured the length of the hose that remained on the threaded end, as well as the part that was on the jet head, plus the middle tube, the total length was 8.5 inches.


From Amazon I bought the smallest zip ties I could find: ($5)


I also bought the replacement hose: ($10)



I was able to get the hose over the threaded end and zip tie it with the plastic clip in place. I trimmed off the remainder of zip tie. Put back into collar, turn a bit to avoid the two rails, and push the hose out the other end. I then attached that end to the big head and made sure the two pegs lined up. Pushing that back in and pulling on the threaded part while also making sure it aligned in the tracks. Also made sure both ends were zip tied.


Did this four times. Screwed all 4 jets in. Got new manifolds from the spa dealer (mine were missing the black O-ring). Got the manifold hooked up. Filled the tub. Turned on jets...


One set worked, other didn't. Scratched head. Remembered about a post where someone had jets that were brand new, but the air pressure just wasn't high enough to move the jets. Turned a couple of dials on my tub... SUCCESS!


The local HotSprings store sells these jets for $130 after tax apiece, times 4 jets would have been $520 USD. 


I would add that if anyone ends up having a salt cell go bad, I highly recommend the Hot Tub Wizard. He has a cell that instead of being $900 (what dealer quoted) is $200. You can replace it yourself. The best news? He provides a cheat sheet of how to keep your tub going for decades by not having to buy the chemicals through the dealer (dealer charges me $17 for the salt, which I need every time I empty the tub. He points out where you can get it for $2).


Thanks to everyone who contributed to this thread. $15 and your knowledge saved me quite a lot.

Thanks to all, I am just glad that my fumbling ended up being a success for so many others, besides fixing my MM issues. 

I better learn to start drinking more beer!

Thanks, Randy M
