I bought an 1973 Mirrocraft boat last January. It came with an 8hp Honda 4 stroke outboard. The serial number of the motor is: BACL-1001686. Does anyone out in Tin Boat land have any idea what year it is? Do I buy parts from a Honda dealer only? The outboard is white and blue and looks like it may be a '70's vintage. Any opinion in regards to this motor would be appreciated.
