    Has anyone had their thermostat housing break?

    I was just running down the lake and the motor started slowing down. I stopped and water was pouring out from the cowl. The thermostat housing broke off. Looks like cheap plastic. 2020 175 pro xs fs

    If you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!

    This is quite unusual... but it's certainly possible. Need to get the engine in to an Authorized Mercury Dealer for inspection/repair.

    Seen it a couple times. Whoever rigged it likely dropped the cowling on it and cracked it. I had one injest water from this and hydro lock it

    How bad was the motor damaged? Mine looks like it may have a little water in the oil. I take it in to have it looked at on the 4th.

    It threw rods out the side. Customer said it failed at wide open. New powerhead was sent.

    I was literally running 40 mph when it happened. I was very happy with the 175 pro xs fs on my 189 trx until this happened though.
