Used the Stern oil change pump. It just took a few minutes to pump all the oil out, as opposed to the Top Sider which can take over twenty minutes.
I have the wrench for the filter housing cap but do not have an extension. It was difficult to take it off, but I just hand tightened it using the plate and the bolts on the wrench, for the next time.
My question is, how important is 25 Nm? It is not leaking any oil.
