Very common, they make HP flame arrestors that are way larger and more open than others, the one we used on the raceboat was good for 800 plus HP (1000 CFM) but cost like $300, it was about 10" in diameter and 5" high, was aluminum and made of wire mesh, not the expanded metal stuff..We ran a sock over it too (some rivers are dusty)...

Good find BTW.

Here you go! This is a standard one but check it out, (less than we paid in 2000).

this has me curious... What type of flame arrestor was on the boat? I have a Hardin scoop and a Hardin flame arrestor and now I am wondering if I remove it if I could see the same type of results.

A little different for me 550 hp 850 carb BBF its making more hp and whats more fuel then the flame arrestor will flow air just my o2.
