I am considering purchasing a repossessed fishing boat with a 2003 yamaha hpdi vmax 175 hp. I would appreciate any information about the reliability of this motor and the recommended maintance schedule. For example what should I do with this motor when I get it considering I do not have any maintence records. The boat is well maintained from apperarance and I assume this would be a boat with less than200 hours on the motor. Thanks Rog
