Re: Raw Water Cooled for 35 Years?
My Yanmar 3gmd has the crank handle listed as a part (parts book), as I think most small Hp Yanmars list it. I do not think I have enough space to turn crank, but the battery powered drill you mention might work.
I also have fears of getting hurt if crank keeps spinning after engine start. My mother tells me stories how my gradfather cut his hands starting there crank start cars.
