Hi Windstalker,
Sounds like you need a cure and some prevention for water and algae in the fuel tank. Water can enter the tank in a number of ways but the classic is caused by the air in the tank expanding and contracting through a 24 hour day. When the air inside the tank contracts it draws in humid air from the outside that drops its moisture in the form of condensation. This fails to the bottom of the tank where it is difficult to remove. The prevention part is to always leave the boat with a full tank. Water sitting in the tank can corrode through the bottom of the tank causing pin hole fuel leaks. If water ever overwhelms the water fuel separator and gets injected into the cylinder the steam flash will instantly ruin the injector and the injection pump is then in jeopardy. I think step one for anyone with water in the fuel that is lucky enough to be in thriving marine community is to hire a fuel polishing service. These services clean the tank and fuel and put cleaned fuel back in the tank. I used one after having a problem when the boat was on SF Bay. I was very happy with the results. Once we moved the boat inland I added a new larger Racor Turbo 500 water separator/fuel filter and an Algae-X in a very accessible location. The drain on the turbo 500 allows me to easily siphon all the useable fuel from the tank into diesel jerry cans which I donate to a local business with tractors. The tractor owner knows the source of the fuel and has never seen a problem. I do it every other year so I know I'm starting with clean fresh fuel. I can't swear the Algae-X works but I have not seen any traces of algae in a filter since it was installed. You can also purchase a water alarm for the bowl of the water fuel separator. That gives you a chance to drain the bowl long before it gets filled.

I find when my fuel tank is less that half full I get water or something in the line and the engine quits. I have a fuel strainer installed in the line so it is easy to clear the water and pump up the pressure, but I still have to bleed the air out of the line. If I don't bleed the air I get symptoms similar to yours.

Changing fuel filters would be a good place to start. If you have the original Facet fuel pump, check the strainer on the bottom of the pump. > Don, #6293, Niceville.

The engine starts fine, and idles okay. Initially, when I advance the throttle, the motor dies, almost like being flooded in a gas engine.. It is then somewhat difficult to restart (usually 3 or 4 tries), then it runs normally and smoothly, with no hesitation. The same behavior occurs after sailing around for a while. The mmotor starts okay, but wont initially power up. > > I suspect a dirty fuel filter or dirty injectors or maybe a dirty air filter.
