Well, it still isn't right. In the water it wont idle for more than about 45 seconds. When I'm moving it runs great, doesnt skip a beat at any speed but after I drop it down to idle it dies, sometimes almost immediately and sometimes after about 30-45 seconds. If it sits for more than 5 minutes I have to pump the primer again and hit the enrichment valve to get it to start. Obviously it's a fuel issue still, maybe the fuel pump, or something with the lines? But then again it runs great at speed, had it out a few times and haven't had a single problem while cruising around so I'm not entirely sure where to go from here.

What rpm's is the idle set at?
In gear in the water. 750-800
​In the driveway, 1100

Does the ball pump up firm? no? thenthe pump might be bad?
Yes? then the inline connectors might be bad and sucking air.

Idle is about 900 in the water, the ball pumps firm but it takes a few more pumps than it used to and it seems to not be quite as hard as it used to get.

Your primer could be bad?
​The diaphragm in the fuel pump and the primer could be bad?
