[C320-list] Yanmar 3GM30F Component Part Numbers

Alan,

Yes, this helps. Lots of good info here. After I sent my message I looked up
the OIL filter on line and the smaller one indeed seems to be the correct
one. There was a note on one website that it is smaller than the original
Yanmar filter, as you also indicated.

Some comments on your list:

I don't think you want to use "green" anti-freeze. I think it's supposed to
be red. I used a red colored Shell product that was recommended by a marine
store.

Not sure why the R/W impeller has a funny number. May be an equivalent part.

Thanks,

Following are notes I made at commissioning of Sea Shadow.  Yanmar did
change the fuel filter a few years ago and it is much smaller than the
original.  Hope this helps! - Allan Field

Deck Hardware Rebedding (from Catalina Rendezvous notes)

Rebed every 3-4 years.
Use gasket scraper to get old caulk off.
Solvent – use mineral spirits to clean old caulk; no acetone.
Caulk – “Boat Life Life Seal” above water line.  3M101 below water line.
Silicone only around Plexiglas.
3M 5200 – use only if it never needs to come up.
Stress cracks – natural; not a problem.
Catalina barrier is vinylester (entire hull, per Gerry).  Better underwater
than polyester.  Frequently used in blister repair while others use epoxy.

Hi, 

Is there a list of recommended (or required) part numbers for the Yanmar
3GM30F engine components such as filters and belts? I thought there was a
list on the C320 IA site but I couldn't locate it. The part numbers below
are what a local marine shop provided to me but the oil filter looks very
small compared to the non-Yanmar one that's on my engine now. The whole
assortment of parts only cost about $100 including tax which I thought was
not a bad deal. Maybe others will have a different opinion. 

I also looked through my C320 owners manual, a Yanmar engine book that came
with the boat, and a Clymer Yanmar Engine book but I could not find a list
of recommended part numbers. I find that odd unless they keep changing the
numbers over the years, or I just missed it.

Model: Yanmar 3GM30F
S/N: E27901

Yanmar Part Numbers:
Fuel filter: 104500-55710
Oil filter (Yanmar): 119305-35151
Alternator belt: 25132-003700
Raw water belt: 104511-78780
Raw water impeller: X08810B
Fuel filter element: Racor R15T
