The problem I'm having is the motor starts fine but once out at 80% throttle for 10 minutes the engine loses power. I have about 20% thrust at full speed. Enough to limp back to dock. I took it out of the water and ran it at home. I realized my fuel filter is empty. I pump up the bulb and watch the filter fill up. Then it slowly empties. I replaced the fuel pump, gas tank and line to the motor. Any thoughts? Compression is excellent in both cylinders.
 
Maybe that your fuel pump is no longer strong enough to draw fuel as needed, have you tried pumping bulb when it starts losing power? Jut a thought.
