Not really, the bay is like chocolate milk. Despite watching for debris, we actually hit a 2x4 piece of what was likely dock decking coming up the Blackwater,(which is less stained than Escambia or Pcola bay), hit it square on the lower unit, scared the crap outta us. Fortunately it did not seem to do any obvious damage, but we didn't see it as it was waterlogged and barely floating apparently. cut a little split into it, maybe and inch deep, guess it hit the tapered 'sharp' part of the engine.What about debris, can you see well enough to spot it in the bay?
We picked up a wood chair floating in the waves as well, just because we didn't want anyone else to hit that too.
