Call the manufacturer and ask for a replacement "Title" I don't think it is called title but whatever it is called you will need it with the hull #.. Obviously the yak has never been registered for a motor if it doesn't have a sticker.
I had no problem registering a used Malibu.
I used a 7# 18# thrust and top speed would run circles around a Hobie.
Unless laws have changed, which they may have, but you didn't have to register a boat that was powered under 10 hp, thus the 9.9 came out. I don't think a trolling motor qualifies as a power that requires registering.
http://www.flhsmv.gov/dmv/faqboat.html#3 I only use a small trolling motor when I use my 12 foot vessel in the canal behind my house. Do I have to register my vessel? Yes, all vessels used on public waterways with any kind of motor must be titled and registered.
Is a non-powered vessel required to be registered and titled? If the non-motor powered vessel is less than 16 feet in length, it is not required to be registered or titled. However, if the vessel is 16 feet or more in length, it is required to be registered and titled.
http://myfwc.com/boating/regulations/#nogo All vessels, with the exception of non-motor-powered vessels less than 16 feet in length, non-motor-powered canoes, kayaks, racing shells, or rowing sculls, regardless of length, must be registered through your local
I would suggest that you either call or drop in to the local tag office & explain the situation to them. That way you will get the straight scoop & it may not be as hard as you may think. I registered & titled a small tin boat I bought second hand in Alabama with just a hand written bill of sale. I don’t know where you are located, but the people up here in Milton are pretty cool about explaining everything & helping you out.
