This sounds a little strange to me. The boat should have a prop that allows max engine RPM. Your dealer may mean that normal cruising rpm should be about 3200, which is just about right. Too many people under rev their engine thinking they are extending its life when just the opposite is happening. You can run right up to engine max with no harm and cruise all day at 3200.
