    This is a long known issue for Yamaha . . . . i.e. I have a 2005 that has this. So that's way over a decade the mfr has had to address this issue, yet we still see this happening.
    While I hear standing water to blame as well, I bet there's likely also some manufacturing process in-play. Being that the foot-wells are a confined space, angle of paint spray, and perhaps not able to get a decent layer of primer/sealant in that tight area could be contributing factors for adhesion and degassing. Not sure if pre-programmed robots are doing the painting or if humans are.

    They are being painted by electrostatic application equipment on a robot using PPG primer, base & clear coat. My company quoted painting them but we could not fit them through our paint line.

    That is unless it changed in the last two years.

    I will definitely look for those pics. I have the modified Deans plate in there but I suspect it should work or I may go to the pump tunnel although I would rather not drill anymore holes, ha.

    Also any idea on the part numbers for the drain fittings and check valves. I was looking but the diagram won't load up on this pc or browser for some reason. Thanks again

    Edit: i found all the parts on another pc browser. For anyone looking into it on the drawings the footwell drains are located in the bilge category. Im waiting for jettribe to make there new covers then im installing these drains next year during off season. I gotta paint now anyways by then at this point

    I didn't get pics this weekend but I do have the part numbers

    drain plug
    F3X-U2255-00-00 (need 2)

    Check Valve
    F3X-U7767-00-00 (need 1)

    Connector
    F3X-U8377-00-00 (need 2)


    I bought 1/2" hose and 5/8" heater hose from the parts store instead of buying the Yamaha hoses. I used a 5/8" barbed tee to bring the two drains together and a PEX 1/2" to 3/8" fitting from Lowe's to increase the 1/2" from the check valve to the hose that fits onto the barb for the transom plate. 5/8" tubing is used from the drains to the check valve; after the check valve it is reduced to 1/2".

    Thatís a fact mine has the tiny bubbles in upper footwell area as well. Mines a 2016 FZR . Iím no paint specialist but it seems pretty apparent their is a defective paint error in the whole matter and not a water sitting issue , however water may have been the catalyst ie; normal use in water having started the decay of bubbling appearance I say this because I canít for sure remembering seeing this when brand new ....btw I have only 43 hrs now ... imo paint defect In Yamahas production ..no doubt at all....

    Any base coat and clear coat combination is not designed to be submerged in liquid for any length of time. I work as a paint process engineer for the automotive industry. We do a submersion test on our parts and they will all bubble over a period of time. Why the engineers didn't create a drainage system for the foot wells along time ago is beyond me. I know cost is a factor but you would think quality complaints would have outweighed the costs.

    ^THIS

    Yea seriously can't say it any better.

    I will inevitably have to repaint. Going to do the footwell drains in the off season.

    I just got off the phone with Jettribe. They are working on new covers that fit aftermarket bars as well. I told them all about this thread and the yamaha footwell issues and how there is a strong demand for good reliable cover. Told them the Riva bars are at 32 inch to 30 inch etc. May not be a complete solution but still going to be a damn good cover and probably keep 98 percent of the water out. That with drains will do the trick.

    Funny thing is I checked my girlfriends ski yesterday that sits on its own single lift on the same pier just like mine and the footwells are bone frickin dry!!!!! factory cover too...which is obviously better that the yami cover...
