I have a 4.6 meter nautiglass half cab hull whiich is constucted out of fiber glass and in excellent condition. I want to buy a new outboard for it but i dont know how big an engine i can fit to it . Does any one know any person that built these hulls as it was built in 1977. it has a 55hp on it now which struggles with four people and fishind gear in it and thats without a head wind! I think it would take a 90hp to 100hp 2 stoke with out any problems. <br />The rating plate on the hull is gone and i just want to know for insurance reasons just so i dont go to big in hp's. Thanks if ya can help regards Moorbee.
