K&N Arrestors Make Power or Not?
#3
And their numbers and recomendations on their site are wrong. If you dig deep enough and do the number crunching, you will see that a size similar to the size of your flame arrestor is very restrictive and you will have to go much bigger to get the same flow. Then theres the lack of visible Coast Guard approval to give you more problems.

A buddy of mine had a little trouble today. He was stopped by the USCG in Baltimore's inner harbor. They boarded his 23' Rinker Captiva. They got him for the engine compartment blower, one life jacket and the K&N flame arrestor. He tried to explain that the flame arrestor was "marine approved" but because it did not say "Coast Guard approved" they said he had to remove it. They towed him to shore where he either had to make the repairs or pull the boat. He made the repairs which included installing the old flame arrestor (he just put the K&N on today).
I went to the K&N website, it states that it is "marine approved per SAE J1928" but it does not say that it is "Coast Guard approved". I am calling them tomorrow to try to get an answer to this question.
I currently have a K&N and I don't want to be put in the same position if I am stopped.
He said he would just keep his old flame arrestor in the boat but if these are not "Coast Guard approved" will our insurance company have a reason to deny our claim if we ever had a problem?
I went to the USCG website and found this:
"The following frames address the 15 areas that are the main inspection items of the VSC. Five of these items: Personal Flotation Device (PFD or life jacket), Fire extinguishers, Flame arresters, Visual Distress Signals (VDS), and Marine Sanitation Devices (MSDs) must be either Coast Guard approved or have a Underwriters Laboratory (UL) or Society of Automotive Engineers (SAE) number. All references to these items in the following frames are assumed to meet this criteria."
I talked to the Coast Guard this morning. They told me that the USCG regulations had changed as of January 2004 to include "SAE approved" flame arrestors. They do not have to carry the "Coast Guard approved" label.
