hi everyone I will be doing my first oil change on my yanmar in the spring. I purchased the oil filter but I'm not at the boat and won't be until this spring. Not knowing where exactly the oil filter is located on the engine can someone tell me if I will need an oil wrench and if so what type will work best. I'll need to purchase in the states befor I go to the boat. Thanks for the hrlp

Never hurts to have one but so far I have not needed one sense you are traveling and my not be able to get one there go ahead and get one they are less than 10 dollars ....take your new filter the the parts store and match it up with the correct size there about 3 different sizes

I like the wrenches that fit on the end of the filter and you turn with your socket wrench. The band type are difficult to fit and tighten. At least for me.

P.S. You do have a method to pump out the oil don't you? Usually you can't drain the oil out the bottom of the pan and need to suck it out of the dip stick hole.

You can see it in the photo below located just below the Alternator. Mine is a 2gm without the FW heat exchanger, so a little simpler, but the Filter should be in the same spot.

I had to buy a suction system to drain mine. Bought this one, but a closeout version that had a black canister for less money. WEST MARINE Manual Oil Changer - 2.9 Quart

Most folks should be able to remove the filter with just their hands. If it's slippery just wrap a rag around it.
They should never be torqued on tight, but sometimes the rubber sticks a bit.

Not all filters that will fit your engine can be worked with a fixed size wrench so I prefer a band wrench made out of rubber that wraps around the filter and tightens as you twist. You are probably going to use a Yanmar filter but even those I have used in different sizes. Later on specially overseas you will likely use any filter that is readily available.

Thanks for the replies. Usually a wrench is not needed but I want to be prepared just in case. I agree with Benny that the band wrench is best however without knowing where the filter was located I was not certain that I could use this type wrench. In looking at Pateco pic I think it will be fine...and I did purchase a pump similar to what Pateco recommended. Thanks again

Most filter "how to's" I've read say: "Tighten by hand, then turn 1/4 more." I have no idea how one would do this without a filter wrench or strap.

As you prepare to change oil, remember to run the engine before to heat the oil so it will flow easier. Also, my yard manager suggests to punch a hole in the top of the old filter to allow the oil to drain out of it, otherwise there is always major dripping from the yanmar regardless of the use of plastic bags.

Filter location is shown as so:

The hi-tech little gizmo under the oil filter is used to avoid oil spills onto the block when the filter is first unscrewed. A strap type wrench fits nicely with all this room.

Note Stu's remark for instructions on installing every oil filter I've seen. The only way to go 1/4 turn past hand tight is to use a wrench so it's not coming off without a wrench.

The diameter of the Yanmar oil filter is 3".

Ralph, what is the diameter of the copper tubing? (Ingenious tool, BTW. I really admire you guys' creativity.)

BTW, there has been endless discussions/debates about the value of using Yanmar filters. I think we do agree that Yanmar does not make its own filters, though the Yanmar branded filter may be made to Yanmar specs. Some have cut the little devils open to compare filtering elements and pressure relief springs. You might do a search to decide which to buy. Ralph's catchment tube is patent pending, or should be if it's not.

Since you don't know the diameter of the filter you are going to remove, buy a good quality strap type filter removal tool. The size is adjustable for almost any filter size you'll encounter. They also come in handy for loosening jar tops and gripping other cylindrical shaped objects like stubborn hoses.

If all else fails, take hammer + screwdriver. Drive screwdriver thru side of filter. Use screwdriver to turn off filter. Cost? Nothing if you already have a hammer and screwdriver. Yes, it is messy, but will get the job done. Like others have said, don't over tighten.
