Vetus Sea Strainer Wrench - Saildrive oil filler mod

My sea strainer cover always seems to be too tight to loosen easily by hand, even though I lubed the threads and always hand tighten it, so this tool is super handy. I also seem to have the same issue with the Sail Drive oil cap, so I modified this great design to add a slot in the handle to loosen that cap with the same tool and made the handle a little longer.

This now makes engine checks much easier to perform.
