merc oil filter part # 35-840634k01 this is the same on the 600 sci, i have been trying to find a cross for mine , if you find a cross let me know

wix # 57003r
wix #5122r are both the same size but show for racing only i think the thread size is different.

none of the mobil 1 filters matched so far

Not sure which way this tread went. The 600 sci and the 700 sci, do not use the same oil filter. Or at least the 600's we had, and 700's we now have don't. The 600's you can cross with a Fram HP 4.

So it looks like Merc wants more flow and sacrifices filtration on it's bigger motors?

SO a Wix Racing or Fram HP series is what they spec for?

I just called Wix & Fram. They have never seen this merc part #35-840634K01..........mmmmm

Hydrocruiser

Either have I...

I have in my hand a merc oil filter off my 2008 600 sci motor

#35-840634k01 merc part # (that is the correct part # as its the same on the new one i just put on boat sat.

its about 4 1/2 " wide 6 1/4 tall with a 1 1/2 " thread opening

I just changed oil last weekend . In checking with wix based on measurements

the # 57003r
# 5122r both look the same size as the merc filter

Mercruiser cross numbers for K&N filters....

Cross for more filters..

So my research found that the 600 Mercury #'s cross with a Fram HP-4 = Wix 51060R = K&N 07-0029 = MOROSO 22460

If I were fortunate to have a pair of 600's I would go with one of the filters above as they are built for "Racing".

I would probably use the K&N filters. As the new ones have really outstanding flow and capture as well. The MSRP is $14.00 and Autozone and PepBoys have them for around $10.00.

I like what Moroso is saying here...a balance of flow and filtering..27 micron filtration (I think Wix was 60 mics if I recall.) This Moroso filter is in my mind equal to a K&N... lots of flow...proper engine oil pressures...max. engine life. Not that Wix is a bad filter or anything.

The 700's cross with a Fram HP-6 = Wix 51222R, 57003R, = Moroso 51222R, 57003R. M0bil-1 501; No K&N #'s.

I think we hav it nailed for the 600/700 engines...agree?

Beak Boater

Its just a coincidence I guess, that the Wix part # and the Moroso part # is the same for the 700 sci??

Hydrocruiser

Gotta wonder...but the Moroso has different specs for filtration I believe.

Hydrocruiser, I also prefer the Mobil 1 filters. Do you know what the cross reference part number is from the HP6 to Mobil 1?
