I am looking into buying a fifteen foot MFG boat (1962) With a johnson 55hp and a trailer. My first question is will my 1995 ford ranger haul this? My second question is this hp big enough to tube and water ski with kids around age 10-15 or adults all weighing under 150lbs each? And my final question is how much would you expect this to be to register in Maine? (First the boat then the trailer). Also do i need any insurance if i'm using it on a very small lake? if so how much would this cost????
