For engines with jacket water heaters 2000 watts and higher, Clarke will now only offer a 230 volt option.  Clarke has found that the wiring and circuit sizes can be too small for the 115 volt heaters and will now only offer 230 volt heaters for the following engine series:  

  • JW6H
  • JX6H
  • DQ6H
  • DR8H
  • DS0H
  • DT2H
Clarke will keep some 115 volt heaters in stock for heater and/or engine replacements for the JW6H, JX6H, DQ6H, DR8H and DS0H series engines.

We apologize for any inconvenience which may occur with this change.
