Before Buying That Boat Consider having the engine, drivetrain, and associated systems evaluated by a professional marine diesel mechanic. This inspection process will produce much information concerning the most expensive parts of the vessel, and will usually result in a price reduction on the boat that more than covers the inspection fee. This procedure will also help to avoid the unfortunate circumstance of buying a boat only to discover that the engine, transmission, prop shaft, fuel system, or exhaust system, etc,etc, require extensive repairs.
