Here are links showing some of the internal differences in oil filters.

http://www.aus-cartalk.com/auspoc/te...tm#OilResearch

http://www.scuderiaciriani.com/rx7/oil_filter_study/



The first link doesn't come up (please re-check)
The second link has tons on info yes, but most
of the filters shown all say "filter effeciency unknown".
So, what IS the standard filter number for the 3.0L ?
Since the 3.0L is pretty much a GM Chevy 181 CID,
I would think that its a garden verity PH1, PH2, PH3, no ?
I also find it odd that the oil filter is all secret-secret,
but yet they don't use AIR filters! Yea, you are on the
water and there is typically no road dust etc., but on my
new 2005 Bayliner 175 Capri, I'm seeing a lot of real
fine white fiberglass dust all over the engine. I reckon
this is left over sanding dust left over from manufacturing.

But thanks for that info - I'll take the time to read all
of the info in the second link.



I just tried both links and they work for me.



Use any high quality filter that you chose.

Ah, well, thats what I'm asking you here...
WHAT is the regular over the counter number
for a Merc 3.0L GM 181 CID ?? PH-"WHAT" ?


The main difference between auto
and marine are that marine filters have a more corrosion resistant finish.
As any boat mechanic will tell you, that many engines are destroyed by a

rusted thru oil filter that decides to let go at the most inoportune
moment.

Rusted from the OUTside ? yer kidding.. I can't imagine that.
So the orange paint on a Fram filter will rust ? hum, must be a
salt thing, cause the orange Fram, or the yellow Penzoil filter I
have on my trucks, and outdoor equipment never ever rusted.
Worse case, just hit the orange Fram with a coat of gloss black
Krylon, and should be pretty much tthe same thing, no ?


If you inspect and change them often, you should be OK

Cool, thanks.
