Sorry guys but I am having issues with it bogging down under load after it runs a while and then stop and fish. On the first start everything was fine started right up let warm up ran to the first fishing spot ,was a little slow on getting plane but had traveled thru long no wake zone . After about a hour went to start and started fine but was idling a little rough revved a little to clean out and when went to open it up would just bog out and not want to run . That is pretty much the way the rest of the day went. At times you could get on plane but would start to die down . I searched it several but don't really see a good way to correct .I have already checked compression and it 140 all six cylinders . I am going to change the plugs because they look fouled and possibly clean the carbs . Are there any thing else to try?
