The Complete pre-purchase survey normally consists of three parts:
Pre-purchase Survey Considerations:
A buyer may elect to limit the pre-purchase survey to the in-water inspection, or a combination of the above. REMEMBER, if you do this, it is only a snapshot of the vessel's complex systems, not a complete pre-purchase survey. Not recommended.
While the Pre-Purchase survey does include a general exterior inspection and operation of the propulsion systems, the internal condition of the engine(s) and various drive systems cannot normally be evaluated by the Marine Surveyor. This phase should only be accomplished by an Accredited or Certified Engine surveyor, or an experienced, impartial mechanic, Certified on the particular engine(s) being considered. Engine surveys are highly recommended, especially when considering the purchase of high performance, and/or very expensive vessels, and older boats with diesel engines.
Oil sample analysis:
Oil sample analysis is generally recommended for boats with diesel or high performance engines. Although onetime sampling and analysis may not be conclusive, it can detect certain immediate problems, and certainly provide valuable information as to the need for further testing or impending component failure.
Corrosion and destructive testing:
Depending on the findings of the Pre-Purchase survey, various other testing methods can be employed to determine the condition of bonding and electrical systems, structural components and environmental hazards.
