First post here, this is a great site and I have read a ton of info already. I have a 99 javilon venom with a johnson 90 and a 91 alum duracraft with a mariner 25hp. I just picked up the duracraft and was wondering if there was a place where you could see the parts break down of my mariner engine? I have not purchased a manual yet but figured I would ask if there was a parts break down. I know for my bike and truck I could just download one from a site but found nothing for boats. Thanks for any help. I really just want to see how everything is located and how it fits together.
