I just purchased your 300w heater for my Eastern Downeast 27 because the boat is in a slip year round and the marine mechanic recommended it. After some internet research i purchased one of the Xtreme units . Since I use my boat year round on lake Norman and below freezing is common during the winter i can use the boat with confidence.
Great product. I have it hardwired into the 120 shore power and the installation couldn’t have been easier.
