Hi folks, this is my 1st post. My question is will this be plenty of motor for my new 1648 weldbilt . The boat weighs about 300 lbs empty. I now have a 15 hp johnny on my 1436 and i dont think it will have enough power . I come accross the 20 for a sweet deal (375.00 ). What do you guys think? BTW I am adding diamond plate to the floor and front deck on the boat. ILL POST PICS. LATER.....................Thanks........Cat Hog.
