I typed in Champion in the main search bar and looked for an answer but didnt find it exactly. I know there not Honda quiet but there also a 1/3rd of the price. Im use to either hearing my Onan run in the Class C or a big old school Coleman with 5-8 hp Briggs so I cant compare. Need some real world opinions on this. It will be at the back of the boat facing whatever way its quietest and I will be at the front of the boat. Thanks guys!
