1720 keywest / 90 hp 2 stroke yamaha primer ball is sucking flat as a pancake at any rpm above idle.
Here's what i've done already- removed ball and spring from inline check valve at the tank, cleaned the pickup tube that enters the tank witch has a screen on the bottom, replaced fuel line from tank to fuel water seperator,replaced fuel primer ball, replaced filter on the fuel water seperator witch is after the primer ball so that should not be causing the obstruction. I also removed the vent line and was able to blow through it from hull to tank with no problem. While water testing it yesterday, the ball sucked flat and when this happens it takes 5 minutes for the ball to reshape it's self. I got undet the consol and pulled the fuel line off the tank and the ball opned up emediately, i pulled out the pick up tube and the screen was clean. seems like somthing is obstructing the pick up tube every time we go on a plane.
the onlything i can think of is to put an inline fuel filter away from the tank and remove the screen from the pick up tube and hope to catch what ever it is in the fuel line outside of the tank.
Anyone ever had a semmiler issue befor?
