    I finally got to the heater and the core is shot. fan works. ( looks like a single speed 4" bilge fan )

    I know some have said they used ford ranger , and cougar heater cores. But So far I cant match this one.

    The core outer measurments are 7 1/4" X 6" X 2"

    the outlets are on the end. I have found plenty with the outlets on the side.

    can anyone tell me where I might find a new one.

    Or have any info on the Acuheat company.

    thanks

    Acuheat is the "model" Heatercraft is the company that makes them.
    Take a look at the cover of the install manual.
    Yours is a Acuheat 100 made by Heatercraft.

        That is what I have in my boat for a heater core. Saved a few bucks over a heatercraft and I like getting Summit's catalog. ;-)

          My heater is blowing cold air, does this mean my heater core is shot? I have a 1 yr warranty on the motor so I'm guessing I won't bother with it until the end of the season but I was just wondering.

            When your feet are wet, your heater core is shot. Make sure that your valve on the engine is open allowing hot water to flow through your heater.

                  Yep, follow the hose if you need to. It will probably look like a garden spigot.

                      I can't find this valve anywhere. Can anyone with the 8.1 tell me which side of the motor I should be looking on.

                        Replacment core for Acu-Heat 100

                        I found this core - think it will work in the Acu-Heat 100 series ?

                        Looks to be almost identical in size...
                        Would it matter if I mixed up the inlet and outlet ?

                          Bringing up a old thread. We got down to -10 this February. We took boat out today for the first time and motor was fine and no block damage but the heater core is shot. a lot of nice steamy water kicked out of the bilge. Just had both the shaft and rudder seal replaced by marina and their mechanic was still around. He bypassed the heater hose to stop the issue. 07 X2 with 3 vent. What size replacement core do we need to order.

                            I’ve been scouring the web for a replacement core. I saw this thread and the core identified by bryangold but I was really hoping to find one that was closer to the actual dimensions. I found a core at advanced auto for a 2000 Kia Sportage that only gave the height, which should have fit so I gave it a try knowing I could return it if it was too wide. It was a no go, it turned out to be about 1/4 too big all the way around. I went back to the internet and stumbled across the exact same core bryangold referenced but on eBay for half the price (https://www.ebay.com/itm/291976867101).
                            Since I really wasn’t finding anything else close I decided to give it a go. It arrived yesterday and with some modifications to the box I think it’ll work just fine. Left to right it’s about perfect coming in at just 1/8” narrower. Top to bottom the cooling fin portion of the core is 3/4” shorter and the overall height is 1” shorter. Lastly, the base of the core won’t set in the original track because it’s 1/4” wider.

                            I went to Home Depot and picked up a section of 1-5/8” 25 gauge steel drywall track to boost the core to the top of the box and fill in the extra space. (https://www.homedepot.com/p/ClarkDie...5-15/305981784)

                            The core sat perfectly into that track but was still a little short. I ended up flipping the original track and connected both tracks together to the box (pic attached).

                            To fill the little bit of space on the sides I applied some 1” wide joint filler dense foam tape.

                            I had to punch new holes in the cover because neither the inlet nor outlet line up with the existing holes but I’m happy to report that the inlet and outlet are the same diameter as the original (5/8”). I used a 1/2” punch and it worked perfectly.

                            I sealed off the original holes with aluminum duct tape inside and out then reassembled the box. It all came back together amazingly well. We’ll find out in the spring how well it actually works.
