I have a 2009 Xstar with the LY6 400 motor. I have had it for 2 years now, I purchased the boat with 40 hours and it now has 160 hours on it. I have all service done @ Mastercraft dealership, and always do what they recommended or what needs to be serviced. The boat has been amazing with zero problems. It is kept indoors at all times.
This weekend we were on the lake, I had just put the boat in the water and filled a 900 pound sac on the drivers side rear locker pad. We were surfing for about 1 hour with 5 people in the boat. As I came back slowly to pick up the rider I put the boat in Neutral and talked to the rider for a while, I went to put the boat in reverse it made a horrible grinding sound and didn't ingage. We were pretty much at a complete stop when I shifted into reverse. I immideatly shut the boat off. I let it sit while I checked the fluid level of the 15/40 motor oil for the tranny, it was full, clean and didn't smell burned at all.
At this point I emtied the sac and put it away allowing the boat to sit for a while. I started the boat and tried shifting into into gear to move forward, it made the grinding sound and then went into gear after the grinding sound for a couple seconds, once it was in gear and engaged everything sounded totally normal, we were able to adjust speed from very slowing moving to increased speed and drove back to where my anchor was stationed without any problems or noise.. I left it for the evening and checked it out again in the am. Once again, tranny oil was clean, didn't smell burned and was full. This time it wouldn't not engage into gear. It would only make the girding sound.
As we were pulled back to the dock with the boat in neutral, it made the grinding sound the entire way at 5mph it was pretty loud. Any ideas? I looked at my warranty and it states it is warrantied for 3 years, that means it would have just expired
any suggestions? Should I contact Mastercraft directly? My dealer has been less than helpful in the past having things warrantied that I have had problems with.
