A marine engine survey is an in depth mechanical inspection of the engine(s) on a boat or yacht. This is not an inspection that just any surveyor can perform. I specifically inspect the engine and transmissions, the download on the EC. I perform a sea trial under weight testing, and back down testing to insure engine mounts. Furthermore, I test the throttle and gear controls for proper operation, block heater testing if applicable, the start and stop functions throughout the boat and in the engine room, and review the service records to determine if there has been any deferred maintenance. Lastly, I will pull oil and coolant samples.
