I am New to the Board. I run a 1974 Eliminator Mini DayCruiser. it is 21ft but they clasify it as 23 because of the swim deck. The boat is in the shop having a Legend pump with stainless a impeller put it. I am moving the motor back 11 inches and putting on upgraded intake hardware,droop,and divertor. I am running a bbc with a tweak here and there. Not the fastest in the world but I am shooting for 75mph on a Daycruiser. Not a drag boat but a damn respectable family boat.
