andymckinley Posted July 26, 2020 Share Posted July 26, 2020 Where is the heater core in an 2008 AirNautique 211? I think mine might be leaking/cracked as there is moisture in my heater tubes and my bilge runs more often than usual. Link to comment Share on other sites More sharing options...
Baller PatM Posted July 26, 2020 Baller Share Posted July 26, 2020 I would go on the Planet Nautique forum. They would have more people familiar with that boat Link to comment Share on other sites More sharing options...
Baller BraceMaker Posted July 26, 2020 Baller Share Posted July 26, 2020 Where do the heater ducts come out? I'd bet its up in front of the drivers seat behind the front seat back. You should see the ducts run up to it. Is the water coming out of the bilge hot? Link to comment Share on other sites More sharing options...
Baller Jmoski Posted July 26, 2020 Baller Share Posted July 26, 2020 Most likely it’s behind the kick panel at the drivers feet, you should be able to undo a few screws to remove it, but remove it carefully if your on/off/bilge switch is on the panel. In the interim, if you get a short section of heater hose, you can short circuit/bypass the heating core by detaching the feed & return lines off the engine block and attaching the new section hose as a bypass.

andymckinley Posted July 26, 2020 Author Share Posted July 26, 2020 Thank you Pat M. I am trying that forum too. BraceMaker and Jmoski ... Heater ducts come out under the seat behind the driver's seat (typical v-drive layout) and by the driver's feet. Water is coming out of the bilge hot/warm. Accessing and finding is my issue. I took the main floor panel out yesterday and then the kick plate (this has fuses mounted to it). The heater core is not directly under/behind these panels. From looking at the owner's manual diagram, reading other posts, and following the heater ducts as best I can, I think it might be in front of the driver's seat or below the throttle on the starboard side. Again, so far I can not figure out how to access. Would pictures help? I will take a look at the bypass option. Link to comment Share on other sites More sharing options...
Baller PatM Posted July 26, 2020 Baller Share Posted July 26, 2020 Also check closer to the engine dog house. I think the heater it self may be on the drivers side of the boat towards the back of the boat Link to comment Share on other sites More sharing options...
Baller Jmoski Posted July 26, 2020 Baller Share Posted July 26, 2020 The manual - https://www.planetnautique.com/CorrectCraftManuals/2008/2008vdrive.pdf Isn’t that helpful. Nor is the PCM engine manual which is also on PN. Based on pic below - see if it’s under the cooler that’s beneath the cushion behind the drivers seat, that is the other likely spot for it and correlates with the picture.

andymckinley Posted July 28, 2020 Author Share Posted July 28, 2020 Spent 30 minutes at lunch and found the following. The heat exchanger is leaking when I run the boat. See pics. The 2nd pic is after driving for 5 minutes at 30 mph and the water was very hot. Later tonight or tomorrow I am going to take the heat exchanger out and assess. Is this broken if it is leaking or is possible that I just need to seal it? Link to comment Share on other sites More sharing options...
Baller oldjeep Posted July 28, 2020 Baller Share Posted July 28, 2020 Just need to replace the core. Typically not even worth trying to have a radiator shop fix it. Or just bypass it, never understood heaters in a boat - when it is cold put on more clothes. (And yes it gets cold here) As an interim or permanent solution just get a piece of tube that fits inside the in and out hoses and clamp them together. Then you can use your boat.

Baller Skoot1123 Posted July 28, 2020 Baller Share Posted July 28, 2020 My experience is just as @oldjeep. Typically that means a new heater core. A radiator shop may be able to fix it if it is a newer model heater. Otherwise a new heater core is in order. Link to comment Share on other sites More sharing options...
Baller skimtb Posted July 28, 2020 Baller Share Posted July 28, 2020 I have heard on the internet (so it must be true) the new cores are stainless or aluminum and last longer. Originally they were automotive cores, which is ok with Auto coolant And non corrosive properties. Add lake water and maybe not so good.... So, benefit to new core is you may be done with the issue permanently. Heater is nice for warm air for your hands and feet as well at into a towel wrapped around you. More clothes don’t always have same effect. Nice feature, even if it adds a few min to winterizing. Link to comment Share on other sites More sharing options...
Baller PatM Posted July 28, 2020 Baller Share Posted July 28, 2020 I've replaced the core and it is a $100.00/ten minute fix. Nautique Parts.com Link to comment Share on other sites More sharing options...
Baller dvskier Posted July 28, 2020 Baller Share Posted July 28, 2020 It’s a $50 fix if you use an auto parts store to acquire the core. Replaced mine about every 4 years or so. Link to comment Share on other sites More sharing options...
Baller Jmoski Posted July 29, 2020 Baller Share Posted July 29, 2020 @andymckinley - glad you found it, what was in front of that rough cut hole/access point? Link to comment Share on other sites More sharing options...
Baller Kwoody51 Posted July 29, 2020 Baller Share Posted July 29, 2020 There is a small, very small, chance it could be a loose hose or a crack in a hose but as others have mentioned your core is likely done. Running raw lake water through the heater cores is very tough on them. Automobiles have highly engineering coolant running through them so they aren't subject to the corrosion that a boat heater core is. May or may not matter but when I'm not planning to use my heater I shut off the valve to it so it doesn't have any lake water running through it. Maybe this is worse as lake water sits in it... I don't know. When my heater core goes out not sure I'll replace it as the accessibility of it is awful! Link to comment Share on other sites More sharing options...
andymckinley Posted July 29, 2020 Author Share Posted July 29, 2020 Thanks everyone. Heading out now to remove over lunch. Jmoski - see pics above for location. It is directly behind the driver seat in a "trash can" / ski glove holder/ netted area. Link to comment Share on other sites More sharing options...
Baller UWSkier Posted July 29, 2020 Baller Share Posted July 29, 2020 At least that's in a pretty easy spot to get to. I've seen some that are a major pain to remove. Link to comment Share on other sites More sharing options...

Baller oldjeep Posted July 29, 2020 Baller Share Posted July 29, 2020 oops - didn't get all the water out last winter. IF you are feeling brave you could just clean it up, apply some flux and use some pipe solder on it. Link to comment Share on other sites More sharing options...
