I think I am having a problem and looking for someone who will listen!! My engine WILL NOT REV ABOVE 5000 RPM'S!!! And yes it was trimmed up down and in the middle doesn't matter. Parker performance data and other owners have all said it should rev between 5800 to 6000 RPM'S. I have taken to two different places and everyone keeps saying change the prop but if Parker and other 2320's will rev this high Why wont mine? The last yamaha dealer said they put it on the computer and it even shows the motor has never been above 5000 rpms and they want to charge me severval hundred to water test because there is not codes. Do they not stand behind manufactures and there data? Anyways I love the boat not so sure about the motor just want it running right so no worries or at least one less when i am offshore. Is there a dealer in the Ocean City, MD. area that is willing to fix the problem instead selling me a prop?
