Re: bayliner model 4387 manuals
Welcome to iboats!
Try calling Bayline customer support at 360-435-5571; they should be able to e-mail you a .pdf of the boat manual. Have your HIN available when you call. The owner's manual supplement for the 1994 version of your boat can be downloaded
here. The engine manual can probably be found in a number of places (factory manual is best); what engine and outdrive do you have?
BTW, e-mail addresses aren't allowed in public posts, so a moderator will undoubtedly be along shortly and remove it.
