I have a 16' carolina skiff dlx with a 2000 honda 25hp 4 stroke tiller model bf25a with electric start on it. I took it out on the river yesterday and it was very slow with 3 guys and some gear in the boat. It would not get on plane and if we were going 12 mph we were going fast. I made everyone get off and with just me on it, it ran about 18 mph. The motor starts right up and idles fine. I doesn't seem like it is missing. Is this normal or what can I do to make sure I'm getting the right speed out of this motor? I can't believe that 25hp is that slow.
