I'm new to this forum, and forums in general. I have a 1978 Starcraft Seafarer 14 and it's titled with HID# as STR090510678. I've searched the internet through and through including this website (iboats) and what little I can find states that the MAX HP is 30HP. My capacity plate is gone. This boat has been in my family since around '93 or '94 and the plate has never been there. So my question is, can someone confirm that the max hp for this boat is in deed 30hp, becuase Im really wanting to upgrade to a 25hp from my 9.9. The transom has only one brace, and some of the things I read about earlier models with the one brace eluded to 20hp max hp. So it's a so confusing to me. Can someone please help. Thanks in advance.
