Water pouring out of heater box

[scott resick]

So today was the day I fired up the boat. Hooked the hose up to the intake and she fired right up. As I waited for the water to come out of the exhaust, I didn't see any. I checked the temp gauge and it wasn't getting hot but I noticed water flowing out from under the bow. Here all the water was coming out of the heater box. Not any of the hoses, but the metal housing. How do I go about figuring this out? New heater? Or can this be repaired?

That sounds like your heater core is shot. The heater should be made by Heatercraft, you can contact them to see if a replacement part is available. You may have to replace the whole fan/heater core assembly, since some of the old style parts are no longer available. I had to on my 03 when the fan failed.

The boat is a 2006 196....if that helps

FYI - you can install shut off valves inline on the existing hoses that go to & from the heater so you can stop the leaking and use the boat. I put them in my old boat, pretty easy to do, $20 in parts from lowe's. Another short term solution is to buy a new piece of heater hose from an auto parts store and create a bypass by hooking it to feed and return connection points on the block.

There is a post over at CorrectCraftFan dealing with this exact issue. Take a read. You can get replacements at NAPA.

Yeah, I added ability to shut off my system a week or two ago... All you gotta do is go get 2 male and 2 female 5/8 barbed hose connectors. Cut the lines and put them in nearby engine compartment where you can reach...5/8 inch lines just like hoses. So simply cut each line put in male on one side, female on the other of each hose where you cut it. So you connect them when system is being used. Then if you have to shut off you disconnect. And use simple hose splitter with each side of splitter (black shut off) in closed position for shut off. (So at top of the y just is not used when using the thing to shut off the system. Just handy to use since it has 2 male ends each with a shut off).

So the side that has the engine put the female hose connector. And put male side of each hose connector on the heater core side. Then you can use the last item pictured to blow out the system since you will have male side of connected on the heater side.

Not sure, but that heater core they used awhile back, used to be the same as the one in a 96 Ford Bronco I had... lol

thanks scottb7, and the others for your help. i am going to do this! should make winterizing way easier too.

This is likely what happened to your core. Mine busted over last year's winter and I just ordered a new replacement. Around $120 I think

This is my version of a bypass valve that I added to the heater lines

If you wanna save money, you can take that to a napa or something and match it up.... I know I used something like this a long time ago....

great help, thank you all!

So I got the Y's plumbed in to bypass the heater. The 96 bronco core was about an inch too wide and NAPA coundnt match any to fit in the box. Im going to try Advanced today. If they cant match it I will build a box to house the bronco core. Thanks for the tips!!

Blamey, I hate to ask, but can you do me a solid? Rmaytee over at ccf found a heater core. I cannot, and im having trouble registering on CCF. Could you PLEASE ask him what the part# is on his new core? Please, and thank you.

Even with those gone, it's so tight it won't be moving anywhere. Also had to cut the openings for the tubes to exit the box. Not a big deal. Once I got it all buttoned up, it started pouring rain. I don't think it's going to let up for a day or two. I'll have to finish this project Monday.

Tim, Do you have a model number for the heater core you found at NAPA?

You bet. 660-3100 I found this from another post, and it ended up working for mine, as shown above, there was some shaving I had to do on the box, but it worked out.
