My P18 came with a brad new B&S outboard. I would not have bought it myself, but I had no choice at that point, and after using it a bit I found it to be better than I expected. I mostly use it in freshwater though I take it into salt water for several days every year. After 3 years there are no issues with the engine other than some surface rust on some bolts etc. I like the simplicity of the engine, though I don't like the noise. It is probably even louder than most 2 cycle engines. My biggest beef with it is that it is a short shaft. With only two people on the boat, if one goes to the bow the propeller starts to cavitate. That is the reason I intend to replace it with a long-shaft engine at some point. If your setup does OK with a short shaft, you might do well with the B&S.
