    My heater does not kick out warm air in my boat. I got a buddy with a x-25 and he said his only kicks out warm air when he is moving along and not toodling around. So last night I went around our local lake a couple times at 35 with the heater on, and still no heat. any ideas?

    Is it blowing cold air? I can only assume you do have the fan switch on to make it blow warm air?

          Not sure then. I was thinking, maybe you wasn't aware of the switch to turn it on?

          I have a 2010 X2 and it blows very warm air when on.

            Yes, that's the one I'm referring to that kicks the fan on.

              is your air "more" warm when going faster?

                I assume that you have the hot water tap open or you dont have one otherwise you would never get hot water to the heater core. Do a search on here for this one. It all has to do with where on your engine are you getting the water from. Some on here have moved the factory location for better hot water at idle. I think most of the discussion was around the LT1, but ICBW.

                  would their just be a switch in the line before the heater core?

                    I have a 2012 X-30 with the MV8 and my friend has a 2012 Moomba and the heater is much warmer on his boat then mine. He also has 2 pull out hoses while I only have 1.

                    If anyone has tips for improving the heat i'd also like to hear them.

                      I also ski behind a buddies 05 malibu, his heat is way way hot. He has a couple put out hoses also. none of mine pull out. can you swap them out with new so they do?

                        and 501, in the straightest way possible, I am insanely jealous of your x-30!!

                          i don't know the specifics of your boat but it should be the same basic design on most boats. you will have an intake hose and a return hose to your core which is basically a radiator like in old houses. hot water comes from the cooling system of the motor and goes through the core and air is blown across it and then through your vents. yes, you can swap out the fixed vents for pull out vents. i think skidim has all the parts. you may not be getting any water to the core. the PO on my boat had just connected the 2 lines at the core when the core started to leak. the fan would still blow air across the core, but it wasn't warm as it wasn't getting water. someone may have put a valve in the hose from the motor to the core. this would be beneficial if the system developed a leak under way and you needed a quick way to shut it off. or it may have been winterized and never reconnected and the hoses are capped at the block.

                          another possibility is maybe your motor isn't hot. i know this sounds silly, but when my thermostat had a piece of the impeller in it, it was stuck way open and the motor wouldn't get above 120 degrees. this yielded only lukewarm air at best out of the heater. once i fixed the t-stat and got up to 160 degrees it was nice and warm again. i do notice that my heat is a little better when i'm underway. this makes sense since the motor is putting off more energy as heat and the water pump is pumping faster. btw this is on an 02 X30 with 2 vents and 1 fan speed.

                            Thanks a lot MC209. It is really a great boat, we love it. It does everything well, handles well and has tons of storage.

                            One more pic.

                              I'm not sure, I haven't really noticed it but we just bought the boat in May so wer really have limited use with the heater but we have used it a night or two going back to the dock and it worked fine. I'll check this weekend.
