You've
checked your finances and you and your family have made a decision. It's time to put an
outboard powered boat in your future. But to get one adequate for your family it looks
like a used boat is in your budget, now the question is how do you know a good used boat
from a bad one. It's a tricky situation. As a boat dealer I buy (in the form of trade-ins)
more used boats in a year than you will buy in a lifetime. And let me tell you from time
to time I still get fooled. My best recommendation is to purchase a used boat from a
qualified reputable dealer whenever possible. However the greatest number of used boats
are sold "driveway to driveway". So here is a step by step guide to buying a
used boat.
TOOLS OF THE TRADE
If you are headed out to examine a used boat
several tools will be needed to properly carry out you evaluation.
| 1) |
Spark plug wrench |
| 2) |
Large straight blade screwdriver |
| 3) |
Compression gauge |
| 4) |
Hydrometer or Load tester |
| 5) |
A set of ear muffs for the motor |
| 6) |
A catch tray for lower unit grease |
THE OPENING QUESTIONS
O.K. you have called a prospective boat owner to
inquire about the boat you saw in the ad, here is a checklist of opening questions.
| 1) |
What year is the boat motor and trailer?. .You will check
this later but don't assume if its a 94 boat that it has a 94 motor. |
| 2) |
How long have you owned this boat? Warning, people who sell
boats after less than one season are usually trying to dump a problem |
| 3) |
Are you the first owner? What is valuable here is if you are
dealing with the fist owner you can trace the entire mechanical history of the unit |
| 4) |
Does this boat have a hour meter? If the answer is no then
forget all the assurances of low hours, without an hour meter you can't ever be sure of
this |
| 5) |
Why are you selling the boat? This is a fair question, If
the individual is buying a larger boat why isn't he trading it in? Very often its because
the owner has an inflated opinion of the value of the boat and is unwilling to trade it
for a fair value. |
| 6) |
Will we have access to a water source when I come to look at
the boat? You need access to a hose at least to properly evaluate the motor |
| 7) |
Will I have an opportunity to lake test the boat? If you
can't drive it don't buy it. |
| 8) |
Could you make sure the batteries are fully charged when I
come to see the boat? Don't assume the batteries in the boat are hot |
| 9) |
Has the motor ever had major engine work, and when? You want
to know the history of the engine. If the answer is yes find out when and by whom and ask
to see the receipts. |
| 10) |
Has the boat ever been in a wreck or had major structure
work? Just like cars a rebuilt wreck has lower resale than one with no structural history |
THE ENGINE EVALUATION
I like to start with the engine because it can
generate the most expensive repair costs if not in good condition.
PHYSICAL EVALUATION
Your eyes can be a valuable tool in assessing
your potential future purchase. First you want to just assess the general condition of the
engine. Look for indications that the lower unit or powerhead has been welded (believe it
or not some people actually do weld up powerheads). Spin the prop and watch the prop shaft
for wobble. Pull the cowl and look the motor over closely. Powerheads are painted after
assembly, look at all the head gaskets. Powerheads are assemblies and if the gaskets
aren't painted then its an indication the motor has been apart. This isn't a bad sign if
the owner has been upfront about the service history.
COMPRESSION CHECK
You need to run a compression test on the
engine. I like to do a compression test after the engine has been run on the hose for a
few minutes. While the engine is running with the cowl off check for fuel/water on exhaust
leaks. Your compression test should come in with each cylinder checking within +/- 10% of
each other.
LOWER UNIT CHECK
After you have run your lake test drain a little
grease from the lower unit (a few thimbles full) into your catch tray. If water comes out
with no grease you have a big problem. If grease comes out looking like coffee double
cream, you may have some water in there and you might need seals. If it was pure water you
can expect some gear damage and shortened gear life.
THE BOAT
Again a visual inspection is where to start.
Crawl under the boat and check it bow to stem for gauges where fiberglass webbing can be
seen. If the glass has turned brown or is soggy you could have serious lamination damage.
Check all of the lids and seats for tears, cracks, and hinge condition. One tip never buy
a used boat in the rain. In the rain many finish problems are hidden when the boat is wet.
Walk on the floors and decks. Soft spots mean big trouble and a very expensive repair. Now
its time to check the transom. First look for stress cracks in the transom. If they are
there its not necessarily more than a cosmetic problem. What you want to do is trim the
motor up and put your weight on it. If those cracks widen or you get any flex in the
transom just walk away. A bad transom is an expensive repair and you don't want any part
of this rig. Lastly load test the batteries, at $70-$90 a piece new batteries can put a
real crimp in you budget. Also if you're not taking the boat with you write down the type
of battery in the boats or mark them. Some people will switch good batteries for weak ones
when they trade. It's sad but true.
LAKE TEST
Never buy a boat without a lake test. First back
the boat in on the trailer. Fill and test the live wells. Then pull the boat back out and
pull the plug (your checking for leaks). Then relaunch the boat. Check every switch and
button, make sure you drive it and then you can really tell if its the rig for you.
Remember that no one can predict the future
durability of any used product. Hopefully this guide will be a good primer for evaluating
a used boat. Remember without careful consideration your "Dream Boat" can turn
into a nightmare quickly.
