Honda EU2000 Exhaust

[patrick brooks]

hoping for information, is it possible to pipe exhaust from Honda eu 2000 generator so gen can be run in lazerett area safely

Exhaust will not be your only problem that is an air cooled engine and needs plenty of fresh air circulation or you could burn it up.

If you do run an exhaust you want to check it very good for leaks you don't want exhaust fumed leaking in to the below deck space


Unless you plan to water inject the exhaust be very careful a hot exhaust pipe could ignite something

There are kits on eBay to extend your exhaust. Just search on eu2000i exhaust extension. The problem with the small generator in an enclosed space such as a lazarette isn't so much heat it's gas fumes. The eu2000i doesn't have a closed loop fuel system and as such fumes could accumulate in the bottom of the space. Without adequate forced air exchange you could have a bomb in there.

Exhaust pipes for these small generators can be wrapped and there are proper thru hull exhaust tips (search on webasto exhaust tip).

Just some thoughts to consider. Good luck.

A few years ago I inquired at the Honda dealer about extending the exhaust on a larger Honda generator so I could leave it in a construction trailer. I was told the lengthening the exhaust creates too much back pressure on the engine and could potentially create a failure situation. Looking on ebay and seeing the kits available, it seems as if they would be closing down the exhaust substantially and could create a problem.

I started going down this road as I have two Hondas.
Ended up with a 3.5 KW Nexgen. Not saying it can't be done but there are a lot of problems to overcome. 12V bilge blower could supply cooling air. But there is just no way around the gasoline in an enclosed space and I doubt the Honda is ignition protected either

I tried this during my summer Cruise. I had a firm weld on a pipe on the exhaust and then connected it to a thru hull made for webasto heaters. Insulated the lazarette, and installed double fans, one in, one out driven by the 12v outlet. The generator works fine for 45-50 minutes then the temp rises and I turned it off. It just seemed like fans couldn't haul enough cold air after the gen came up to working temp. I'll try some larger blowers next year. It will run very silent so it might be worth some more tests before giving up. Be careful with the heat and the exhausts!
