Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Sorry....all I know right now is yamaha f150 2007 4 stroke......I will try and find out more info on this
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
This diagram is the typical fuel system on that engine. Remove the cup on the filter, part 8. Pour what is inside the cup into a clear container. :Then hold that container around the filter, use the primer bulb to pump some fuel into your container. Allow it to sit for a few minutes. Is there more than one layer in the container?

Ok.....will try this.....do I need a special tool to remove filter?.....I was reading online that this may require a special tool?
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
Not for this engine it should not. The filter housing just screws to the base. Standard threads.

Assuming there is water in fuel line tank.....how do I correct?
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
Well you will need to either pump it out or have the fuel that is in the tank cleaned. then you will need to purge the engine fuel system with fresh clean fuel and get it running.
Is the boat on a rack or a trailer?

On my boat lift at dock.....how much should this cost if I take to service center.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
that would depend on how much water is in it, if there is any at all. You would be looking at a few hundred to get the fuel cleaned of any water if that is the cause.

Customer reply replied 2 years ago
any other reasons besides water in fuel to cause issue?.....should probably replace water/separator filter anyway.....
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
There are several other items that could cause this. Fouled plugs, plugged fuel filters, a stuck ring on a piston, lack of fuel pressure, sticking injectors, a bad coil, or just a bad plug. If the alarm was going off, that would open a whole nother can of worms.
