    Water Heater Replacement 3587/4087

    I searched through historical posts but didn't see anything helpful on this topic. It's time to replace the hot water tank on my 4087. The actual installation should be pretty straight forward. My question to any owners of 3587 and 4087 who may have done this job already regards access to remove the old tank and get the new tank into the correct area. It looks to me like there are two possibilities. First would be through the oddly shaped access hatch at the end of the cave. The dimensions of this area I think is slightly too small, but may be big enough if some of the trim is removed on the back side of the wall that holds the hatch. The trim is lightly glassed to to the wall, so this would be a little destructive.

    The other would be to slide the tank laterally to the area in front of the starboard engine, then slide again across the front of the engine to the middle of the boat, then back a bit then up. The tank only weighs about 20 pounds so this wouldn't be hard, if there is room. It looks like maybe if the coolant expansion tank is removed this might work better.

    Anybody out there already had to do this task, and, if so, which way did you go with the removal and replacement of the tank?

      Just noticed your post. I pulled the HWH out through the access hatch in the cave. I did have to cut a small notch out to get it out. It was a triangle shaped notch maybe 3/4" x 3/4" so it is hidden by the hatch cover when put back. Check dimensions on the replacement heater because they can vary a bit. My replacement was the same size as the old one.

        Yes. Thank you. I ended up doing the basically the same thing, though I achieved the notch by knocking out the trim piece that's on the diagonal of the hatch. It was both bolted on and lightly glassed in, so now it's just bolted. Overall, not too hard of a job.

          Just saw your post, and it looks like you completed your water heater project. I did the same a few years back and posted the process here:

            I stumbled across this thread because I need to replace my hot water heater. Can anyone tell me why when I click the link though it goes to the homepage rather than the project details?

              All the links posted prior to the last upgrade do the same. You can start a new thread if you have some questions or PM the member that posted the link, he may still have the pics to share.
