I have a 1998 5.0L Mercruiser
I have a 1998 5.0L Mercruiser 2 barrel. The boat started by running a little surge at 2000 - 3200 rpm. I've cleaned gas screen at carb. Sprayed carb cleaner while boat was running. I noticed there may be a bit to much oil but not crazy high. The boat was running 4750 rpm wot and now it is running 4400 rpm. I boat idle and putts around the lake great. I'm certain this is a carb issue. The engine is also got a slight bog. Like the carb is loading up.
