I?m looking for help from anyone with experience with Suzuki outboards, specifically a 1989 9.9hp. I?ve worked a lot on Johnson/Evinrude outboards, but this Suzuki is?different.

I?m relatively sure I know what the problem is...Low fuel pressure. The outboard starts and idles well but stalls out after running it fast after about 10 seconds. And if I keep priming the fuel bulb, it will keep running well.

So, I figure it?s the fuel pump, right? Well, maybe. Except that I don?t think this outboard even has a fuel pump. I guess that?s the first question I need answered. What pumps the fuel into the carb?

So, how would you go about troubleshooting this? What could it be? All comments are welcome.

Here are some pictures of the outboard, for whatever it?s worth.
