iboats sells the Seloc. Go to the top of the page and look in Boat Parts and Accessories. I have used OEM Merc and Seloc on the same engine, a 90 hp 2002 and I found that I liked the Seloc better and I guess it was the illustrations were better....picture is worth a thousand words sort of thing. You can rent time on here, like I did and have instant access (as soon as you pay for how much time you want) or you can wait for a paper version. I used the rental process and liked that.
