I am glad you realized how difficult is to find used boat in good condition .
It can take you a year or longer to stump on a good buy not to mention on the honest seller -that is like 1 in a million .
I paid lesson for not knowing some things with boats - and how most of local boats can be purely finished ( not sealed ) and how bad patch up job previous owner or owners did including dealerships that fitted outboards without proper sealing of bolts .
Shoddy wiring , left comparing to right hatches not cut in same place on the deck , cracked gelcoat from screws expanding the fiberglass , skew hinges , hatches too small for larger guy if going insde (FC) , non practical shelves ,too many drink holders fitted like it’s a party boat. And I can go on and on. Now with all knowledge , all tools that I had to buy including all materials to fix and modify my boat properly . I can only suggest , finance new boat with new engines and go fish. And even so I would probably spend hours fixing brand new boat as I know it’s not sealed properly. When boat is not sealed, over time you will get foam waterlogged , transom rotten , deck rotten and so on. If you find a good looking used boat - do not hesitate to give asked price but on condition that you will only pay it after you drill many holes to inspect hull for water logging . If all dry like a bone - cash out . If you find wet foam - say good buy . Areas to be checked . Close to front seats where poles goes below deck , close to transom , under fish and fuel hatches . Drill in transom also for wood wetness if it’s older boat with wood.
Also boat must be kept in garage if you want to last many years .
