Florida registration title transfer paid off lien? What to put for sale price

[Boatchick]

If I paid off the lien on someone’s boat $20,000 to the dealer and then the difference of $6000 in cash to the seller. Do I need to claim the $26000 when I transfer the title and register the boat or did I pay any of the sales tax of the original purchase when paying off the lien?
Thanks!

Why would you claim cash transaction - just state 20K purchase price, unless you want to pay more tax

I was hoping I could say I paid the tax to the bank and claim the 6k lol
