Re: Owner manuel or operating manuel
Hope you find one but I wouldnt hold your breath....even if you do find one it generally seems that most manufacturers that even did put one out (most only supplied a data sheet with dry weights, max hp and optional accessories) generally had it filled with pretty generic information about a boat in general. if you are looking for engine information you would do better getting manuals on the power plant for instance if it is a mercruiser get a mercruiser manual, boat manufacturers typically wired the power plants to their specifications.
You'd probably do better starting threads with specific questions you might have and try to find answers that way.
