I was clearing out the loft recently and came across some manuals that may be of use.
Two are for outboards and may be of little interest, but one is the for the Yanmar inboard (currently £25 from the Book Depository). This and the Johnson Inboard are as new.

If anyone is interested please drop me an email.
I'd like £10 plus £4 postage.
