My condolences on your father-in-law. I can relate, my mother-in-law just passed as well.
I really like the Mariner Seville. Nice boat. Almost bought one, but we just could not get past the fact that the original owner installed a 69 hp engine! Too small in my opinion. If that had been a John Deere 125 HP we would probably own that boat now.
Welcome aboard the forum and enjoy the boat.
