went out for a day on the water and all was good until I anchored up for a beach walk. Returned to boat and engine would not torn over as if it was dead. After fooling around with the obvious appears the engine is stuck in forward and will not shift to neutral or reverse keeping the engine from turning over.

Had noticed a trip before was grinding a little when shifting to reverse.

How do I go about adjusting the shift cable which is what I assume is the issue.

Do I have to drop the lower unit to do the repair. If so what parts, tools do I need.

Not much fun running 224 with only one 115hp operating.
