You should expect to not want to come back to the dock!!! And resist the urge to sit in your new boat all night.
Here's a list I put together a couple years ago with help from a lot of the forum members on what to look for when inspecting a new boat. Maybe some of this will help.
Boat: (model and hull id #)
Trailer: (model and serial #)
Motor: (Serial #) Verify manufacture date
Price: Verify quoted price includes freight, prep, battery, prop, etc “ready to run”, plus tax/title/reg.
Options: Check off your order list.
BOAT: Check above options, Check for defects, Check railings for sharp edges, check pontoon tubes for slag, look for metal drill filings, open/close all storage areas, open/close all gates, check seat adjustments, tilt steering, electrical circuits and switches, stereo/speakers, raise/lower bimini, check LEDs, bow lights, mast light, horn, spare keys
TRAILER: Turn signal and brake lights work, test surge brakes, verify bunks and guides tight, all bolts tight, carpet/glides secure and complete, wiring attached securely
MOTOR: Size/model correct, check manufacture date, prop correct size/brand
TEST RIDE: Check depth graph, power trim/tilt, check steering (full left, full right, smooth operation), TOP SPEED?
PAPERS: Documents and Manuals, including motor and trailer?
Questions:
Call insurance company, verify coverage before moving boat.
Verify 2” hitch ball.
Ask about motor break-in period and warm-up period.
Registration grace period?
Bring:
Electrical adapter (trailer)
Tongue Lock
Hitch Lock
Tie Downs
GPS (for speed test)
