I recently was given a small boat with an early 90's Honda 9.9 4-stroke with an electric starter. It hasnt been operated since 2002, The oil looked fine but I will change before going out. I was surprised that the motor started at all but it will start fine--has a good stream of water coming out of it, but it will die after 3-5 minutes running on idle. You can pump the bulb and it will run forever. I suspect a fuel pump is the problem. I took the fuel line off from the pump to the carb while it was running at idle and it is pumping fuel but I have no way of knowing if it is a weak stream or not I just know it was pumping.
I had the tank valve open and even tried with the cap off. There was a small fuel leak where the fuel line connects to the motor but I fixed this by splicing the fuel line and removing this connector until I can get a replacement.
There are two holes on the opposite side of the engine case from the water discharge opening--one looked like it was plugged with dirt from an insect--I cleaned it out with a small screw driver but I am not sure if it is open or not further up--could this be a air hose to the motor and could this cause the problem?
The model number is BF9.9A and it had another number stamped in the motor frame I am assuming it is the serial #: BABS:1001490 can someone tell me the year of this motor?
