One of the first questions we get when someone comes up to a boat is whether she has diesel or gas. Now it’s a good idea to know how you plan to use the boat before you buy so this is an important question. If you are going to use the boat as a waterfront condo and only take it out occasionally, then a gas engine is best. If you are going to take the boat to the stream as many weekends as possible, than a diesel is best. To help you know what a boat has if there is no one around to ask, we give you this tip: Diesel’s gota breathe, if the side vents are large or plentiful, then it’s a diesel. If they are small or a few, then it’s a gas. Just like us, the harder something works, the more air it needs. Take a guess at which one that is. Didn’t know you would have a test, didja!!
