I bought a 1989 searay with a mercruiser 3.0l. Bought as is. It started up when we got it. The first problem is that it wouldnt rev up or get going on the water. Figured out it was old gas. As I ran through the gas, it started running on higher rpms and gained alot of speed. After the gas was almost gone, i figured i would rebuild the carbs. I bought a rebuild kit. i cleaned everything, and put in all new gaskets and jets. It starts fine, but doesnt sound real well in idle. When i take off the throttle cable and give it a little gas, it revs up, but comes down real slow. I am wondering what could be causing this. Maybe i measured the float levels wrong or something like that. I made the float level at 9/16 or 14mm. also, i adjusted the pump rod by bending it to 29 mm. now the idle speed screw doesnt touch. I am pretty sure it is something to do with the carbs. this is my first boat, so i am figuring it out as i go. i appreciate any suggestions or ideas. if you need more info, i will do my best to inform you.
thanks
