Here is the check list I used to buy this boat. Most is cut and pasted but I added a few things, also:
Boat Inspection 081409
1. Check for bare fiberglass below the waterline. Cause for rejection.
2. Check for scratches, damage, chips in gelcoat.
3. Inspect and photograph hull thoroughly. Crawl around in jump suit.
4. Check stringers for wood rot and strength
5. Check transom and stern drive for flexing (lift up on lower unit), leaks.
6. Check all lights, horn, electrics.
7. Check engine:
Compression
Vacuum readings
Oil pressure
Oil leaks
Assume it's going to need an impeller
Water leaks
General wiring, condition of wires
Hoses
Engine compartment condition
Owner/mechanic abuse
Milky Oil on dipstick or under breather cap
With large screwdriver, check for water in lower unit
Pull the lower unit oil and look for milky colored oil, i.e. water in lower unit
Spin the prop shaft to be sure it's not bent i.e. uneven wobbly spin. If it's locked up and in neutral, somethings wrong.
Look at the condition of the prop/skeg (i.e. bent)
Take it for a test drive and run it wide open and check the max rpms rated for the motor, ie you don't want excessive overage in rpms rated for the motor and also know what the min water pressure is for your motor
Power lift work? Is there an up-lock for drive?
Was boat used in saltwater?
Check charging voltage
Check battery and batt box mounting
8. Check for dry bilge before lake testing.
9. Check for oil leaks in bilge.
10. Check for bilge pump.
11. Check for stopper plug (transom)
12. Check for water leaks while on lake and after pulled out of the water.
13. Check floor for soft spots.
14. Check for wood rot in storeage compartments.
15. Check function and condition of walk-thru window and door.
16. Check all gauges and instruments.
17. Check trailer, overall condition:
Tires
Steel structure
Salt water use?
Condition of tie down straps
Condition of tires
Condition of wheel bearings
Condition of hull supports
Safety chains included?
18. Contact former owner and get an idea of maintenance, problems and how the boat was used.
19. Boat Inspection:
1. Do not pick the boat up in the rain. You can't make a good evaluation on the condition of a boat in the rain. It makes it very hard to find the gouges/stress cracks, flaws etc.
2. Start from one end of the boat and work your way around it in. Rub your hands and scan with your eyes all along the side of the boat looking for scratches, stress cracks, etc. especially around the console and splash well area.
3. Look at the keel very closely especially around the U bolt where you hook it up with the winch and make sure the U bolt is attached firmly.
4. Get on your back and look under the actual hull between the tires and the trailer tongue of the boat between the bunkers. If you hit something with a boat it is going to hit toward the back of the boat ie the Pad area. Be looking for fiberglass exposure ie matting, major gouges etc.
5. Get on your back right under the motor and look at the very back of the pad. Another popular place to hit an object. If the hull shows very little scratches and use chances are pretty good you got a GREAT boat!
6. Take a look at the bilge area and notice if there is any water in there. If so drain the water take the boat for a test drive and recheck the bilge (ie boat leaks). Any water in the bilge after a short short ride can mean a very noticeable leak on a longer trip!
7. Make sure all of the electronics work i.e. bilge pumps, battery charger, fish finders, rpm gauge, water pressure gauge, lights.
8. Look for anything obvious in all the storage compartments.
20. Check power head if it?s been welded. Cause for rejection.
21. Check to see if gaskets are painted or not.
22. Tools needed for inspection:
Large screwdriver
Tool kit
Compression gauge
Oil pressure gauge
Vacuum gauge
Tire gauge
Rags
Large adjustable wrench
Hammer
Camera
Ground wire
Starter push button
Volt Amp meter
Wax, polish, compound
23. Check finish for restorability, compound, polish, wax.
