today i fired up my Yanmar YSM12 and ran it about 4 minutes( 5 gal. bucket) to rinse out the pink stuff for the year. I want/ need to chage the oil I borrowed a dipstick style pump from a friend, a tommorow will repeat the engine process to heat it up alittle, and try the pump. Any suggestions on types of oil? Don't see any obvious filter to change. Is there? also there ar 2 oil fittings. 1 in front to add new oil, and 1 in back of engine. do i need to pump out both. add oil to both? or are they connected

Filter Yes
My bet is there IS a spin on filter; as you face the engine, look down and on the right-yes there underneath that alternater. The oil fill is on the top of the engine. The oil fill on the back is for the transmission. I suggest you either find an owners manual or have an experienced person before you fly solo on this.

Make Sure
Make sure you run the engine 15 or more to get the oil hot,it needs to be hot and thin to pump out and check to make sure its all out before adding new stuff. I don't know your model engine but should be a filter maybe under the alternator and have plenty of paper towels and try useing zip lock bag around filter when taking off. I use 15w40 rotella by shell and the tranny is the rear one which you can change after motoring around with same oil. nick

my yse 12 had........................
a permanent spin type filter, it had a turn handle on front of the engine with three bolts in a tryangle pattern holding it in. also the rear fitting your talking about may be the trans which may require a different oil. regards, mike

Remember
Remember to first remove the oil filler cap else you may have difficulty in pumping. Also - the oil is HOT so be careful if you are using a metal cased pump. Trick - just loosen the filter and then put a plastic bag over it to finally unscrew it. Catches all the black oil a treat.

Here's the deal . . .
The Service Manual for the YSM 12 suggest 10W30 diesel grade (CP etc.) motor oil. I use puppy pads, or plastic backed absorbent pads to place under the engine and on the sole. The others are correct about having the engine warm. I pump the old oil into a 2 gallon plastic gas can marked "oil" in Magic Marker. I take it with me for disposal when I have the oil changed on the truck. Some waste recycling centers have oil disposal drops. The oil filter is located in the lower front adjacent to the dipstick. It has a spin handle and is held in place with three bolts. You are supposed to turn this handle a quarter turn each time you check the oil which is before each engine start up. The handle, plate and filter is removed as single unit. Observe the line up of the filter element in the engine. There is a notch that should be (as memory serves me) at the 2 o'clock position. The filter is spin type. By spinning the filter it clears the filter media which is metal. After removal, you can rinse the filter with a little diesel fuel. Dry it and continue to clean it in new clean oil. Use and old pie pan filled with oil and swoosh the filter through the oil to clean and saturate it. The only part that needs to be replaced is a gasket. If it is in good shape, forget it. Replacements are available at WM. As stated, the filler in the back is for the transmission. You pump it out separately from the engine. According to the Service Manual, use the same type oil as used for the engine.
