A couple of things you need to be REAL careful with. Ask me how I know!
The fitting for the water hose at the transom is plastic. Be careful with it when you remove the old water hose. After you remove the clamp, slice carefully with a razor knife without damaging the plastic fitting.
Now here's the REAL bad one...the small oil hose on the other side. That little bulkhead fitting is also plastic and if you break it, like I did, you are going to have to contort and jam your hands way behind the engine blindly with a lot of cursing. Believe me, you don't want to break that little fitting. It's boarder line on pulling the engine. I was lucky to get it done. So, slice that small hose carefully and DON'T pull on that hose to get it off. It's just a small plastic hose barb.
