I am confused (not hard to do), yesterday I had the boat hooked up to the hose. Water was exiting through center of the prop. I know that is normal, but it seemed more water was coming out through the exhaust area. The motor temp was good and wasn't over heating at all. Is this normall? Yes I know I should read my manual, but I didn't have a chance to last night... I was hoping to cheat online. Thanks,
