I am not so sure I would call that place a better choice. Can you get a specific factory service manual for a specific engine? Or are the manuals they offer '1 to 1000HP and covering years 1903 to Present'? (All in one book)
I looked at tenkiller and all I saw was clymer manuals. <br />Marine engines did have one for my 79 140 but it was $95. ouch..That's why its good to have a friend like Piniongear he sent me 8 pages from his factory service manual which are way better than anything in my clymer..
