I know you are not asking a question, or for a response, but. . .
While I feel really bad for first time boat buyers when I hear about these bad experiences, they can be avoided. There are many experienced boaters on here that always warn new boat buyers NOT to buy boats sight unseen, have it thoroughly checked out first, and NEVER buy a boat you have not taken out for an on the water test run first. . .
It's a hard pill so swallow, I know - now you know, and hopefully another person looking to buy a good used boat for the first time, will also know. . .
