The SK was only made in 99. They had twin 717's, so not quite as powerful. And yes, they have a bow cover, not a bow seat. Its made just for additional storage. They do look kinda cool though, with either the red or yellow gelocoat on the hull.
The 98 model has the twin 787's. Its the one I have, and I love it. Even though its all white in color, that doesnt really matter with the right graphics package
The later models, early 2000's, had the Merc. engines. I dont reccomend them, simply because they arent as reliable, and many Merc dealers, as well as Jet boat dealers, will not offer service for them. I've had larger, non-jet boats with Merc engines, and they all sucked too. The starters went bad all the time and the cylinders always filled with water.
I love my 787's. They are easy to maintain and I have not had any issues. This has actually been the most reliable boat I've experienced. And that includes brand new ones. Sure, there are minor issues that come up (i've has the exhaust duct come loose) but thats relatively easy stuff to fix, and then youre right back on the water.
If i ever need any help on engine overhaul, I'll be sure to contact you, haha.
I will post new pics tonight when I get a chance. I have tons of them. My wife loves it (and, drives it quite well too), and I'm sure yours would too!
