I just bought an old mark twain boat with a 70Hp Chrysler. When I run it acts like it is running out of fuel. I pump the primer but it never really gets real hard. We were out saturday and it started to act up, and my buddy squeezed the primer and we took off. We got the boat to 30mph when it has been running 15-20mph. What do I need to do? New primer?

More likely a new fuel pump diaphragm.
