My boat won't idle or runs rough

Boy! This could be caused by a lot of different things.

First thing probably is to check the fuel. Do you have any? If so and your boat has been sitting a while without being prepped for storage the fuel might just be bad. Another problem we have here in the South is condensation. A partially full tank can condense water vapor into liquid water which is why you should fill your tank(s) after every use. By the way, if you have a vehicle or any other gasoline powered equipment that often sits for a week or so between use this can be a problem for it also. The less fuel in a tank the more room for condensation. And we all know how well water burns in an engine.

If the fuel seems good and it is reaching the engine then I would check the electrical system. Is it getting a strong spark? Be careful checking this. Having your hand in the wrong place while turning over the engine can be a shocking experience. If it is getting fuel and a good strong spark then you are going to need a professional marine mechanic unless you are gifted in this area.

If there is a weak spark then, again, there are a multitude of things. Diagnosing this kind of a problem would be impossible here. There are just too many different configurations. Outboards or inboards/sterndrives, carburetors or fuel injected, points and distributor or electronic ignition, and so on. The best thing for both of us is for you to give us a call. We can give fast service and a reasonable price combined with the convince of coming to you.
