2000 sea ray with a 5.0 EFI. I have owned this well maintained boat for 150 hours. Never a problem. Yesterday I had to travel 10 miles in rough seas to get back. Lot of pitching going on. Was cruising at 3200 rpm's when I started to lose power,dropped a few hundred r's, and I could hear it back popping through the arrestor. Backed out of it, and it idled smooth. resumed the trip at 3200 for the remaining 5 miles, no problem. I'm sure if it happened once it will happen again. Any ideas?
