On my 2004 Hunter 33 I have a Force10 (Kuuma) model 405001 5 gallon water heater. Recently it has developed a bad sulfur smell. I know - time to replace the anode...or so I thought. It looks like this particular water heater does not have an anode (see link), or at least one that is servicable. I have tried running clean water through it for twenty or thirty minutes with no luck. Short of replacing (this apparently obsolete) water heater are there any other suggestions?
