Aloha, I have been researching the make, model and year of my boat and from everything I've read it seems to be a Glasspar/Larson make and either a Flying V-17 or Citation model and late 60's early 70's. And today, low and behold I found a small plate mounted on the transom (11-704967). I've included a picture of the plate and the boat. I'm hoping someone knows how to read this HIN number and tell me what I actually have. Thanks for any help you can give me.
