MY 175 is bogging out of the hole some. Also, it bogs badly whin I go to load it on the trailer...Almost to the point where I have to get out and winch it up. Do you think new plugs will help, or could it be carb problems. The boat runs like a champ...Just seemd to bog under heavy load. I also think it could be the engine angle when loading, but not much can be done about that. Thanks in advance for the help.![]()
