    Water Coming From Cowl 2015 Pro XS 150hp

    When driving at very low speeds and the motor trimmed up even a little bit I get water dripping out the cowl, I ran it with the cowl off and did not see any leaks from anywhere at idle. Is this normal? If not what could I be dealing with? Thanks.

    Not normal. Water leak somewhere inside the cowling, perhaps the pitot tubing (coming up from the gearcase) which won't leak when sitting still.

    Moving your thread to the correct (2.5L) form. Please be sure to provide your engine's serial number when posting. Thanks!

Is this something to be concerned about?
    Please take a moment to review the ANNOUNCEMENTS at the top of the Forum.

    Then, please open your OWN SEPARATE POST for your engine, rather than hi-jacking another member's post with questions about your engine. This is the second time in two days that I've had to remove a post from you, in this thread.

    Thank you for your cooperation.
