I don't think there is anything in particular about a NEWPORT that requires a specialized list of items to check. The REFERENCE section already contains very well written articles on the topics of buying a classic Boston Whaler boat, assessing used outboard engines, and proper trailer set up.
Twenty years ago I wrote an article offering advice for purchasing used Boston Whaler boats. I don't think anything has changed in the last twenty years that would make the information in that article obsolete. See
Buying Classic Boston Whaler Boatshttp://continuouswave.com/whaler/reference/buying.htmlFifteen years ago I wrote an article offering advice for purchasing used outboard engines. I don't think anything has changed in the last fifteen years that would make the information in that article obsolete. See
Assessing Used Outboard Engineshttp://continuouswave.com/whaler/refere ... Check.htmlTwenty years ago I began a series of articles on the topic of trailers for Boston Whaler boats. The information in those several articles will be useful for you. See
Traileringhttp://continuouswave.com/whaler/reference/trailering/I can also offer this advice for
Assesing Used Boat TrailersLocate, inspect, or determine the following on a used boat trailer:
- the manufacturer's name; determine if they are still in business
- the exact model designator for the trailer; this is useful in communicating with the manufacturer
- locate the manufacturer's sticker on the trailer that gives
- the VIN; this will be essential for communicating with the manufacturer and for registering the trailer with a state registration agency
- the capacity or the maximum gross vehicle weight rating
- the date of manufactuer
- visually inspect the trailer for signs of corrosion and obvious signs of oil or grease being thrown from the wheel bearings
- examine the integrity of the winch, particularly the winch strap and eye
- verify the trailer is registered and has a license plate; if not registered and licensed, look for a manufacturer's certificate or origin which may be needed to register the trailer
- check the jack stand for rust or decay
- verify the trailer lighting system works and has a suitable connector; most small trailers use a Flat-Four connector
- verify there are hold-down mechanism that retain the trailer under the boat
- check the tire size, type, load rating, and speed rating; also verify proper inflation has been maintained
- measure and verify proper tongue weight.
Extensive restoration of a used trailer in poor condition can often entail many new component purchases at retail. Creating a road-worthy trailer from a poor condition trailer may end up costing almost as much as a new trailer.
