The boat is a 2007 Stratos with a 200 Yamaha. Trim has been working but sounded like it was low of fluid but was still working. The motor is running. I am going to check it this afternoon but would like to know how the system works before i start trying to figure it out. I don't think it has a leak as oil would be dripping. Also does anyone know if the trim is covered under the engine waranty. Any help I would be thankful Cub48.
