"Hi, I have a OMC 225 (305
"Hi, I have a OMC 225 (305) small block from GM. The guy who owned the boat before me did put a Carburetor for a 454 big block on the small block. The problem is that the carb floods the engine and it tops out at 3500 rpm with a top speed at 17 Mph. It is a stringer 800 with a 21/16 upper in a 24' 1974 Sea Ray. The boat does not go on plane at all due to the low speed. If any one has a idea on either how to adjust the big block carb to the small block or where to get a small block carb. I would be happy to get some ideas."
