Decided to save myself a few bucks and changed the oil in my F150's myself. Spent $120 on 12 quarts of oil (damn!) and $60 on yamah filters. Draining oil was relatively easy and with the crank case empty and the filter upside down..should be no problem right..wroong..filter was still half full of oil which spilled out into the engine cowling...fork...mopped as much as I could and wiped up what was leaking out of the lower cowling....for the 2nd engine I packed oil absorbent rags around the filter housing before removing the filter, but still split oil ...is there anyway to do that...should I have poked a hole in the filter to drain the oil out??? boat is done and ready to be covered for the winter..which really sucks....
