Awesome wake!!! I ride behind a 2000 which is the same hull with a different interior. 8 peeps is the max that fits, we usually have 2-5 on board without an issue.
You don't have to run tons of weight but its mackin with 600 in each rear locker, 300 in the ski locker and another 600-1200 depending on people. There is no stock ballast in a 99' so you can customize it however you want. 1000 lbs makes it really good, more makes it great. You may want to re prop the boat if you pig it out, I like the OJ 14.25x14.5 but a 188.8.131.52 is good too.
This boat was offered with two engines. I prefer the 310 hp as it seems a little more reliable. That being said we run the 330LTR and it has been pretty rock solid other than a water pump. The 310 is a throttle body injection unit the 330 is a multi port fuel injection both are a chevy 350 block.
