Yanmar 1gm10 Oil Change?

[heron237]

I have a small yanmar 1GM10 installed, the oil drain plug is not normally accessible. Thought it would be nifty to fit one of these oil: http://www.jabsco.com/files/18080_43000_0026_09_04.pdf, instead of sucking the oil out of the dipstick hole

My 2GM doesn't even have a drain plug. I use a 60ml syringe with an extension tube thru the dipstick hole and change oil in about 5 minutes. No fancy toys needed (but then again, I don't like spending money so the admiral tells me)
