Ive been having some issues with my carbs. Took the boat to the shop and had them cleaned, apparently they were very bad. The boat runs great now but the shop didn't inspire a lot of confidence and said a lot of times when 4 stroke carbs get dirty they need to be replaced entirely. I don't know a lot about boat motors but if they are any thing like cars/motorcycles a good cleaning and rebuild kit should take care of them for a long time.
Anyone have a similar experience or can maybe give me a little more insight on the inner workings of a carb on a boat motor? Its on my yamaha 50.
