2000 Mariah 180 4.3l 2bbl mercarb.
Boat ran fine two years ago. Last season from day one it ran like crap. Wouldn't come off idle when in gear (in water). I could use neutral and play with the throttle to get the rpms up. If quick, I could drop it in gear and work the throttle. After several attempts it would come off idle and poorly accelerate. After several more attempts, I could get it on plane and it would run near perfect. Once parked the process was restarted.
I can hear that the carb just sounds different under accleration. A different sucking noise. The primaries drip fairly big visible drops.
Am I missing anything other than getting a new carb? If so I am considering the edlebrok 4bbl upgrade.

- Fuel pump has 12v at switch and under oil switch circuit. Unknown pressure.
- Anti-siphon valve is good.
- new fuel filter
- fuel looked clean and heet was added
- Carb was rebuilt with the basic kit. Everything looked good but was rebuilt per directions.
- carb accelerate pump has three settings and I've tried all three.
- engine idles and starts. If able to get on plane it will run near top speed.
