Boat title transfer deadline in Washington
Washington gives the buyer 15 days from the sale date on the bill of sale to complete the boat title transfer at the WA DOL – Spokane Driver Licensing Office in Spokane. Miss the 15-day window and Washington charges a late-transfer penalty of typically $25-50 plus accrued use tax, and the seller can still appear on the title for civil liability if the buyer crashes the vehicle before retitling. Keep your signed bill of sale and the assigned title together and file as soon as you can, even if registration plates will be transferred later.
VIN inspection. WA requires a VIN inspection by a DOL inspector, law enforcement, or licensed vehicle dealer for out-of-state titles with no VIN visible on the vehicle.
File at the WA DOL – Spokane Driver Licensing Office (1208 N Howard St, Spokane, WA 99201). Bring the signed title, the completed Spokane bill of sale, your ID, and payment for the $15.00 title transfer fee plus 8.90% sales tax on the purchase price.
Boat mechanical pre-purchase checklist for Spokane buyers
Before you sign the Spokane bill of sale, walk through this inspection on theboat. A pre-purchase inspection costs $100-200 and routinely uncovers $1,000+ in deferred maintenance — that is the figure you negotiate off the price or walk away from entirely. Use this list as your shortlist when you meet the seller or when a local mechanic looks the vehicle over.
Common mechanical issues to inspect
- Pull the lower unit drain plug and check oil for water (milky color = seal failure)
- Inspect impeller condition — replace every 2 years regardless of hours
- Verify engine compression on all cylinders (especially two-stroke outboards)
- Check stringers and engine bed for rot via screwdriver probe
- Test fuel for ethanol contamination and water in the tank
- Verify steering cable moves freely with no hydraulic leaks at the helm
Safety checkpoints
- Verify Hull Identification Number (HIN) matches registration documents
- Check for delamination, blistering, or water intrusion in fiberglass hulls
- Inspect transom for softness or rot — the most expensive structural repair
- Test all bilge pumps, navigation lights, and required safety equipment
- Confirm USCG-required PFDs, throwable cushion, and visual distress signals are present
- Verify fire extinguisher is current and properly sized for vessel length
Title documentation notes. Boats are titled by state (about 38 states issue boat titles) and require the 12-character Hull Identification Number (HIN), permanently affixed to the transom, to match the title and registration. Federal odometer disclosure does not apply, but most states require a separate watercraft bill of sale and assignment of registration. Vessels over 5 net tons may be USCG-documented instead of state-titled, which involves federal Form CG-1258 rather than a state title.
