I accessed the Honda data base... by the way, you should take the motor in to a Honda Dealer for the Fuel Chamber recall (potentially leaky fuel chamber) Service Bulletin #62. The records indicate that it has not been done. http://marine.honda.com/owners/recalls
Even though your motor is out of warranty, it should be done at no charge.
