Replace 2QM15 Engine zincs

[Tmacmi]

This engine has two zincs, front and back.

The head of the bolt is either a 3/4" or 1", 4 point bolt head (have to go to the boat to measure)

An adjustable wrench will not fit in the area in a fashion that provides enough purchase.

The best solution would be a 4 point socket, but I am having trouble finding one the appropriate sized one.

Has anybody found one or know of a better solution?
