    2015 Yamaha RIDE System, a first look inside the unit. Code 159 VX110 Waverunner

    Well....after only 380 hours on a shiny 2015 waverunner, I finally had a ride motor go out on me. Worst part about the whole thing is that the ski was only 1 month out of warranty. 1300 dollars later apparently this was the first one go out in our area. Dealer says this is the first one they have heard so far, but its not a typical rental ski so its not getting the typical 1000 hours in a year like the other vx models.


    After swapping out both a good working wire harness and also a good working ECU I was still getting the alarm. The only thing left was either the RIDE motor or possibly something with the ride lever on the handle bars. Sometimes the reverse worked, sometimes it didn't. I was intermittently getting a 159 code. I first checked the reverse bucket to make sure it wasn't binding up and after that it was time to take it to Riva and see what their fancy machine said. After having it for a few days they determined the ride motor was the problem. We ordered a new motor and picked up the ski a few days later. Surprisingly the Ride motor install was pretty easy, I will have a step by step posted up over the next day but wanted to share my findings with the PWC world. I have figured out what caused the actual problem and will go over that in a few minuets.


    First off the ride motor replacement is pretty straight forward, one complete unit. Not meant to be serviced but more meant to be replaced. I took my time taking everything apart but it can all be done in less then an hour.


    This is the brand new unit and apparently the only photo I took of this one.





    On the back side of the Ride motor there is a black plastic cover held down by about 13 machine screws and a layer of 5200, this unit is completely sealed. I ended up taking a razor blade box cutter and tapping the blade in the seal and then continue tapping it along the entire outside till I was able to wedge something a little lager inside. Once you get the cover off, this is what you will see







    That black box laying across the top looks to be the control unit, all the wires eventually go in to this and then also go out. 4 hex head bolts to remove that and on to the next layer.





    The next part to come off is the narrow black bar with the red white blue and black wires coming off of it. This appears to be some kind of position sensor. Two screws and its off







    Four 10mm bolts removes this bracket that holds the output shaft down.









    Motor and gears







    Removed









    As it turns out, the output shaft with that gear on it is seized up, It was very difficult to move back and forth with a large set of pliers, I am going to try and press the shaft out and clean it up and see if it can be reused again. Everything else is spotless and shows no sign of failure. I put power to the worm gear motor and it spun just fine. We are going to contact yamaha to see if there is anything they might be able to do for us, but we aren't expecting much.

    I am going to add a few more photos when I get back to the shop today or tomorrow.

    I had to have this ski for several tours and full day rentals, the new part has already been used. Its not really a big deal now, while it was an expensive part, we were prepared for it to happen at some point. It inevitably cost us substantially more money just to have the ski down for the the week, so now I will just have a backup part for when the next one has an issue.

    I know all about that, and would have gladly bought it when we purchased this ski. However, we own a rental and Riva South knows this. They only offer 1 year warranty for us. I have back up part of nearly every thing for the ski except that ride motor. Apparently it was the first one that Riva has bought so far, and a few people including the service manager gathered around to take a look at it after I opened the box. After spending a bit of time going over the whole thing, I think its pretty robust little unit, no real weak links or silly pins or bolts to go bad. In fact if a bolt on any part inside this ever broke off, nothing would happen. Water intrusion is possible, but they certainly sealed this well. The black plastic shroud that covers the unit is thick and pretty tough too, so a slim chance of that ever breaking either. The plug for the wires is solid and slim chance of the seals ever going bad on that either. There is a built in gasket on the RIDE motor that goes on dry, I wiped down the mating surface on the inside of the hull before bolting the new unit back up.

    I would suggest for those people that have this RIDE system on their skis, to take a hose and rinse the motor and mechanism from the back side of the ski after using it. I can see some corrosion building around the edges that might pose a sealing problem after a few years. I think mine was the product of a defective unit, there is no real reason why this bearing should have failed so soon. I will keep posting updated and more of what I find out about this.

    It looks like a simple fix for a someone that is hands on. Good to have these pictures for reference later on.

    That makes sense not offering the extended warranty to rental facilities. So many places would abuse the heck out of the warranty....Not saying that everyone would. But I'm sure a small percent.

    I would think it is a sealed bearing, a bushing would let water through.
