Marine Boat

Is there any safety issues in using a non marine grade generator on a boat?

The difference between a marine grade 5kw generator and a common home or job site use 5 kw generator is thousands of dollars. I understand salt being an issue but I am on freshwater. As long as I am not spilling fuel are there any safety concerns?

You have more then exhaust fumes to worry about. If the generator has its own gas tank it will be vented into the boat (if you have it in the boat). Getting enough air to cool it would be a problem and how would you get the exhaust out. You could try it on the back of the boat but if there is any wind you have to worry about the station wagon effect, wind swirling around and pulling fumes into the boat. Not to mention it getting wet if a wake hits you from the back. I don't think you would do to well if you got boarded by the police or the USCG as that is not an "approved device" How about putting in an inverter and a dedicated battery for 110 volts instead?
