SO here is an interesting question.

I have a 9.9 Yamaha 4 kicker connected directly to the main fuel line for my 350 Merc. I have the problem with the bulb only on the 350. When I kick up the 350 it drops dramatically and often dies. I pump the bulb on the kicker and that allows the Merc to pick back up. (kicker not even running at the time)I was thinkin that I need to run a seperate fuel tank for my kicker rather than running of the 70 Gal. main tank.

Same problem or something different? Anyone else have a clue or same experience??
