I have someone that is very interested in buying my boat and the motor is still under warranty with the company that rebuilt it and installed it. Everything runs great and no alarms or anything. The buyer wants me to "take it somewhere to have an engine diagnostic done on it to check it over" and is willing to pay for it out of his pocket. Has anyone else ever gotten this request? who even provides this service for an Optimax on the peninsula? I have nothing to hide but just thought it was an odd request. any feedback appreciated.
