doug do you have that specific regulation info as i bought a 9.9 johnson for my 12 foot aluminum , i called whitfields in monroe(licensing place) and they said it didnt need to be licenced, then while fishing the lower snohomish for humpies last year the gamies pulled up and checked our gear licenses etc... and asked why the boat wasnt licensed i told them what whitfields said and they agreed and were on their way so im not sure your info is correct
thanx
