    Default I have a older 75 hp johnson m

    I have a older 75 hp johnson motor. It runs fine in a barrel and when I give it full throttle it runs strong. When I put it on the lake it starts fine but when I apply full throttle it bogs down and will not go to full throttle. Sometimes though it will but not very often. What is the source of my problem???????
