I have experience with both. For relaxing cruises and all around fun, go with the I/O. For hairpin turns that are sure to keep no one in the boat dry, go with the Jet. Either way you've made a good choice. PS: the original poster mentions cost several times. Jet boats suck lots of gas but tend to have lower total operating costs due to less maintenance expense. They are also less expensive to buy, new or used. I presently own a 280 Sundancer and a 3 person PWC.
