UPDATE- Took the boat out this morning. I drained the carbs last weekend. Nothing extraordinary. Anyway, the motor started right up and ran nicely, idling Around 750-1000 rpms. Then, after about two or so minutes, rpm dropped to 500 then the Engine died. When I pumped the ball, it was completely empty. Pumped until firm, started right up, and idled great. I noticed that the bulb was emptying, so I pumped it every 15 or so seconds. I was able to keep the engine running smooth as silk so long as I pumped the ball. Above around 1500 rpm, I didn't have to pump the bulb at all and the engine ran great. Plenty of power and throttle response. At idle speed,I needed to pump the bulb when it started to sputter. Could it be a tired fuel pump?
