your looking for something that doesnt exist.
out of the hundreds of thousands of boat manufacturers over the past 60 years, you could count the number of manufacturers that make manuals on one hand.
normally a boat "manual" is a 4 page safety brochure indicating the pointy end is the bow, the round thing you hold on to will steer the boat and not to go swimming around the prop. there is also a list of servicing dealers.
however, that being stated, the motor will have a manual, links to manuals in the stickies. if you want to buy a manual for your motor, buy a factory manual, stay away from Clymer, Haynes, Seloc.
other stuff such as bilge pumps, cleats, lights, etc are bough from vendors.
that being stated, what information in particular are you looking for?
