    Intermediate Housing Maintenance

    How many of you are doing this? I have a 2019 SVHO. Never done it. 50 hours. Doesn’t seem intuitive as to how to do it and hard to find any information too.

    Remove the plastic pto cover.
    10mm socket long extension. One bolt.

    Lube the mid bearing through the zero grease fitting. Pump the reccomend grease in the housing just until you feel resistance...then you are good to go.

    First lube could take 10-12 pumps.

    Thanks. It’s strange that I hear so little about this. Need to figure out what grease next…

    I did our '21 VXHO, and our '21 FXSVHO about a month ago @ around 70-80 hours.

    The only thing I removed was the electrical box cover. Two latches slide out towards each side of the hull, and then it lifts up and out.

    I never did find a 90 degree angle end for the grease gun.

    It took some gumption and determination to get the fitting on the zerk, but it was doable.

    There was a plastic cap on the zerks from the factory, and one of them ended up lost in the hull so watch for that.

    I'm not sure how much grease I added. A lot. Then i started, and added a few more pumps with it running. Then added some more with it off again.

    We'd had the wave runners out on the lake that day, so they were still hot. The tube of grease was in the hot car, so warm too.

    I never did feel any resistance in the pump handle, but I think that was because of the warmth. I could hear some flatulence of the grease displacing air in there. I assume that was a good thing.

    I didn't have the right (lithium) grease. I use a blue calcium grease cause that's what I had, and operated on the principle of some grease is better than no grease.

    I also was hearing some squeaking noise from moving the steering handle bars, and so I added some grease on the joints back by the pump area. The FX had extra for the pump tilt.

    I hope this helps someone.

    Some may be interested in this thread about relocating the grease zerk for the mid-wall bearing housing.

    I spoke to my local dealer. They said that they don’t ever perform this service. They don’t even sell or carry the Yamaha grease. Also added that in 20 years they haven’t seen a single one fail either.

    so there’s that. Just sharing…don’t shoot the messenger

    The grease is just to lube the seals. It doesn’t take much. They use a sealed bearing in the housing. I put a few pumps in once a year or so.

    If you have a flexible hose on your grease gun you can get the fitting through the hole in the mid wall from the back side.

    At least it’s that way on my GP.
    No need to take anything apart at all
