So, not to get into the middle of this, but air filters are designed to
remove dust particles from the air. My tractors have oil filled air
filters to accomplish this. A boat, operating on a body of water is not
in a high dust environment. I figured this out with my first Atomic 4,
that did not have an air filter and explained it as not being in a high
dust environment. There are a lot of antique motorcycles that have open
ventures that have existed much longer than our boats. I am not opposed
to air filters, but our environment is not one that screams for anything
other than a silencer.

In the first minute of the video you'll see my solution for high flow
AND high efficiency air filter at a reasonable price...well maybe not
reasonable - $48.98!!!

Hey guys,
A new air filter for my Universal M4-30 cost $17 and which seems
expensive for a simple ring of foam rubber sown like a bracelet.
I removed the old oil caked foam from the little screen and
cleaned it up with solvent before installing the new one and had
to flatten the venturi to get a good fit. The parts guy said it
was more of a silencer than a filter. Anybody know of a better
air filter for a diesel engine like mine?

Good to know. Ill check my 30 hp Yanmar. Last sumner running at
WOT for 1/2 hour the motor shut down. It restarted easily and
ran fine. I cleaned the fuel strainer but found no issues. Ill
replace the air filter.

Good to hear. How the heck did the old one get that clogged?
Bad decade for mosquitoes?

While I awaited another day for a marine mechanic to get
around to
addressing my engine problem, while on the boat today, I
thought of
something. I had a new Yanmar air filter on the boat which
I got last
year, which I thought what harm could a new air filter
do....changed out
the old one and replaced with new one, and guess what, in
neutral, the
engine revived up to 3,400 before i stopped....ran the engine
in forward
gear at the slip for another 20 minutes.... shut the engine
off...started again...revved up and down....engine works as
it should.
The problem was a lack of air....explains where the smoke was
coming
from....incomplete combustion...now, with the new air filter,
no smoke.
Thanks to everyone for thoughts/possibilities of what might
be the cause
of my engine issue.
Going for a sail tomorrow.
