I decided to install a marine AM/FM stereo in my boat. Not knowing much about stereo equipment, I went to a local boat dealer and they sold me a Jensen MS30RTL stereo and two Lowrance speakers. When I got it home I noticed that the stereo is 4 channel 160 watt and the speakers are 200 watts each. Is that going to be a problem? Will the stereo be able to effectively drive those speakers? I'm not looking to blast music or anything. Mostly want to be able to listen to ball games when I'm on the water.

You will be fine. Most likely those are max watt ratings which mean virtually nothing. You need the rms ratings.

If you give me the exact model of speakers and stereo I can tell you if you can bridge the 4 channels into 2 effectively doubling the watts supplied to the speakers. But even unbridged you won't have a problem.

I can't think of a stereo that will actually put out 40w per channel. The best will do like 30. Even the newer ones rated at 50 won't do 40.

That being said, if you put 200w to 99.99999% of coax speakers rated for 200w, you'll blow them up. Manufacturers way over rate them, because they know people relate higher wattage ratings to better speakers. I have much higher quality speakers in my truck that are correctly rated at 90 rms and 150 peak, and I have about 80 going to them consistently. They distort if I turn it up anymore.

Moral of the story is that you'll be perfectly fine, and those speakers are matched well to that radio
