"It is an 18H.P. 4-stroke Niss
"It is an 18H.P. 4-stroke Nissan. I have all the parts. I took off the prop and the two bolts behind the prop. The part behind the prop (looks like some type of a hub) does not come off. I have not tried to really pull on it. It souds like there is linkage or something holding it on. Do I have to take the bolts that hold the lower unit off. And if so, I imagine that I have to drain the gear oil first. Then I need to find the oil filter. Does anyone know where that is?"
