I am trying to remove the leg from the swivel bracket on a 1974 Selva 9.9. i have removed 4 screws from the upper and lower brackets but now i cant work out how the bracket and leg seperate, there are rubber shock mounts/ vibration mounts between the bracket and leg. I can't find a manual for this engine. I dont just want to force things apart for obvious reasons. Does anyone have any ideas how to seperate the bracket?
