Both 7.4L mercruiser motors wont go above 3500 rpm. They were running fine 2 weeks ago, took the boat out today and they were very sluggish. Any ideas?

What did you find? Bottom growth? I'm having the same problem now with mine except mine sat for 6 weeks.That's what I thought initially but we rode for quite some time it got a bit better but it seemed the engines weren't getting gas. At first we could only go 11 kts then it went up to 15 kts but they were definitely struggling.
