    Where could this water leak be coming from, FZR?

    Hi guys, I recently installed the kanaflex to Power Filter and went to the canal to try it out, and it made me wonder why I took so long to do it, what a difference!

    Anyways after the test ride I notice a lot more water than usual in the hull, obviously the kanaflex has nothing to do with it. So I re-tighten all the clamps by the exhaust, driveshaft sleeve, and went back out to the canal. Still the same water issue.

    I set the ski on the water and water is not coming in through the transom (at least not that much, a tiny drip is coming in through there, so I guess I will be fixing the notorious transom leak some other time).

    I ran the ski with the seat off and I think water is coming in from the front of the ski, maybe somewhere under the engine, I was able to snap a couple of videos.
    It seems the water rushes in only under load after about 4k RPMS, I don't see any pouring water at idle or low speed.

    The ski has the Riva Cooling Upgrade Kit Stage 1 installed since I bought it new about 5 years ago with no problems at all.

    The entire engine was replaced by Yamaha and installed by Riva just 30 hours ago, they also installed the new style oil cooler.

    I took a glance at the T fitting from the Cooling Upgrade Kit (the hose that goes to the exhaust, and the oil cooler) both seem to be tighten properly.
    I also check the one that crosses to the IC and it also seems to be tighten properly.

    Any ideas where this might be coming in from?

    Thanks in advance,
    Jose

    i think its the coupler housing ...

    my ski coupler is leaking water only under load (full throttle) .

    i checked all of piping transom etc...

    you have to remove the engine to change the coupler bearings and seals .

    i know some guys they don’t remove out the engine out the hull , they just remove the engine a little to the front so that they have space to work with the coupler .

    but you need to remove SC intercooler , everything in front first .

    2014 or 2015? Timing chain? If so how many hours when it went?

    Ski is a 2014 and the timing chain never gave out, engine seize from detonation at around 130 hours

    Question if it was the bearing wouldn’t water be coming in just from sitting in water not even running? And wouldn’t I feel vibrations?

    isa alnoaimi you were right on the money man, unfortunately the bearing is leaking.

    Don't know if there is a thread for this repair yet, but I will start searching. If anybody knows of one please share.
