Re: 16' Gruman Utility
HI, the boat is rated at 40hp you can go to grumman boats and find specs of boat . Yeah to me under powered I have a older boat but with a max 50 hp on it I love my boat fish shallow 18" offshore 10 miles out and pull a tube around the lake.
I would say boat motor trlr no more then a grand more like 600-700 max
the boats do hold value pretty well check nada
hope that helps
