Finally got some free time last week and went through my fuel system. Started at the fitting going into the tank and verified all was good to the motor including a new fuel filter. The rubber seal in the bottom of the water seperator was shot so I ended up replacing it to make sure it wasn't a source for an air leak. I did find that the glass inline filter I added had loosened from vibration and think that was most likely the source of the problem.
My fuel bulb is a West Marine after market (new last year), and I remember a post suggesting using the Evinrude OEM model (see last section).

I got out fishing Sunday morning for a few hours the motor ran fine, no lack of power and jumped right up on plane even with a dirty bottom.

The one thing I noticed when going through the fuel system, there does not seem to be a check valve on the pickup tube. If you disconnect the fuel line going to the filter all fuel drains back into the tank. It primes enough to start but I always see an air pocket in the glass inline filter and the squeeze bulb doesn't always get that solid feel like the float valve is closed and the carbs are full. The engine starts fine, so I'm guessing the leak back is on the tank side. I like having the glass filter ahead of my main filter so I can see if crud is coming from the tank and the screen will stop any chunkies - but once the system is primed I would think that air pocket should clear - it doesn't.
