I don't know the exact name of this thing, but on the outdrive of a 470 mercruiser, just above the prop is the thing that looks like an upside down shark fin that helps control the torque from the prop. Mine is loose and moves side to side. The bolt that holds it in is accessed from the top, through a small hole. The bolt seems to be rusted and or stripped. What is the best way to remove? It's a tight space to get anything into. A friend suggested soaking in WD40 and using a spike type tool to crack or break the bolt, Any suggesstions on getting this thing out so I can replace??
