Re: Crownline 240 EX Opinions
What outdrive?
Initially I believe you will be fine, but truth be known even my 7.4l MPI feels the strain of 10 adults and a tuber. I think in your situation the outdrive may make all the difference, if its a duo prop then I think you will be very happy, with a heavy load and pulling a tube which is probably the biggest load you will pull. The problem with a single prop would be that a heavy load would likely blow the prop out at take off so you will have to ease up a little more then you would a duo prop(but if you floor a duo prop in the same situation you will blow it out too). The main benefit to a duo prop is take off, twin counter rotating props give you alot more bite at take off, on the other side a single prop will most likely have a bit more on the top end. Having more speed on top may not even be a consideration to you. If you were to have a "normal" load say 2 adults and 4 kids either outdrive and your motor would be plenty, 4 adults and 6 kids, your going to feel it. get it out on the water and see what you think.
A 24' boat is a big runabout, but 10 passengers I can tell you from experience gets a little crowded
