I am trying to get some info from people that are having trouble with the serpentine belts in their Mercruiser 350 MAG MPI engine. I was cleaning my boat yesterday and noticed that the belt is ripping. Luckily I wasn't on the water when it tore. I have already lost one belt on the Delta and was stranded. The dealer told me there was a recall on one of the pulleys and it was replaced. They also made sure that the pulleys were aligned. I have heard that many people are having trouble with this same issue. What are you hearing from the dealers and Mercury Marine and is there a solution to this problem other than changing it every 50 hours?
