Recently bought a used boat its a 1989 Four Winns 235 Sundowner so its a 23.5ft boat. My buddy works at a scrap yard found me a trailer thats in working condition (not worried about the looks) and was for a 25ft aluminum boat. Its has the rollers (see attached pic). Any ideas if boat will fit this trailer or how do I find out if it will fit prior to buying it, do you need to take specific measurements or something? Sorry I'm so Naive have no familiarity with trailers not made for a specific boat and how to go about getting one.
