my 40hp is similar. It runs perfectly out of the water (using tank) but missfires under load when pushing the boat. Have been told that it is probably CDI (black box) unit which starts to missfire under load. So expensive to replace I'm trying to find other causes first. Maybe I'll try to repair CDI unit.
