I'm new to boating and looking for my first boat. I'm wanting something big enough to take a few friends out with me but small enough to fit in my garage. Most of what I'm finding in my area that fits that criteria is in the 20-30 year old range. Is there any advice in particular as far as things I should look out for? I've read a lot of posts here and it seems that spongy floors or transoms are money pits waiting to happen. Any powerplants that I need to avoid? The ones I've been able to find in my area are a Mark Twain with 85 hp Johnson, 62 Owens XL 19 with a 283, 78 Chrysler Hydro Vee with 120 hp Chrysler, and an 89 Bayliner. All thankfully have a trailer and none will even come close to the tow rating on my truck so that's not an issue. I appreciate any and all advice and am looking forward to hitting the lake soon!
