    02 F12x - coolant water routing

    Okay.. still working on this 02 F12x - good news: progress is being made. Bad news: still need some help.

    I have the motor in the hull and most of the electrical connections done. I now need help in sorting out the routing of the cooling lines. I have looked in my manual and the diagrams are almost useless (Honda could take a lesson from Kawasaki). This is what I have:

    The large/intake hose coming from the pump runs along the port side, under the motor and hits the valve and splits to the oil cooler and then to the intercooler (got this).

    I also have a hose coming from the top of the oil cooler running along the top of the motor and going.... nowhere.

    I then have the hose coming from the flush attachment near the pump going.... nowhere.

    And I have the hose which runs from the top of the exhaust manifold to part of the exhaust.

    I know that I have a water nipple on the back of the exhaust manifold which needs to connect to something...

    Can somebody give me a decent diagram or walk me through where all of these should end up?

    Thank you.

    So this diagram in your manual didn't help?

    Re: 02 F12x - coolant water routing

    Yep, it still leaves me with questions such as:
    a) Okay, I see that I am missing the hose which goes from the intercooler to the exhaust manifold (easy to fix). I, though, am missing the "to outlet (water outlet joint) and/or don't understand where it is.

    b) Where does the fresh water/flush hose attach? I do not see it anywhere in this drawing.

    c) I also have a black hose coming out of the top of the oil cooler which runs towards the back of the engine (on top). Does it go to anything here?

    So, yes, while this is of some help - I am still left with serious questions...

    A) From Intercooler: Connects to the lower part of the exhaust manifold.

    B) Flush hose attaches to the Plastic Nipple on the rear of the ski.

    C) I think the hose your talking about on the top of the oil cooler is actually a vent hose that goes to the intake. If your not using a factory intake, you can just put a breather filter on it.

    got it.. .thank you. I have the flush hose connected to the hull and nipple. Where on the engine does it connect? At this point it is sitting next to the motor with nowhere to go. Thanks.

    No problem. That one follows the hull around the exhaust water lock then goes underneath the throttle body assembly where it connects about mid point on the engine block.

    Sorry, the f12x water lock is on the opposite side I think. Im used to my R12X. Either way thats where it connects.
