View Full Version : Leak!?

08-06-2007, 09:35 AM
We have discovered a leak! At least we thought so. We have a 2003 X9. I noticed water accumulating in the footwell last weekend. I place my cooler directly behind the driver seat and thought the cooler might be leaking. This weekend I used a different cooler and the leak was worse. I traced it to a hose in front of the footwell. I removed the front seat on the driver's side and found the dripping. I couldn't find a hose leak or split or even a loose connection, but my fat head doesn't fit in such a tight space. The water was hot and only leaks when above idle, so I suppose is it coming out of the engine, but I wouldn't think that would be up front? Anyone have an idea what could be leaking? Thanks for any help.

does the boat have a heater. if so, then the core may be broke.

Only reason hot water would be under the dash is for a heater core, and yours my friend has BUSTED :(

The heater core is leaking. This is a pretty common problem with HeaterCraft heaters of that vintage. Do a search here - lots of posts on the subject.

Pull the core (grey box with motor) and bypass the heater by connecting the two hoses with a double-ended barbed fitting and hose clamps, all of which you can by for about a dollar at amost any hardware store or automotive store. That way you'll still be able to use the boat. Remove the motor/blower from the grey box. Fill the core with water and see if it drips. Assuming it does, call HeaterCraft and tell them. Chances are they'll send you a whole new grey box with heater core inside and in exchange you send them the old one.

Thanks guys! That's great info. Is the best way to access the heater core by removing the panel under the dash?

If your heater was installed at the factory there will be a shut off valve at the engine. The valve looks like a garden hose shut off, just turn it closed and no more hot water on your feet. If your heater was installed aftermarket follow bigmacs advice.

Thanks Corey and bigmac! Found the valve on the side of the manifold. Thank goodness I got a couple of months before heat is needed. I'll give Heatercraft a call. :)
