    yes I see how there would be less maintance also would it be less likely to burn a piston with the efi

    the carb models are easier to mod if that's what you want. i agree that efi models are more reliable, and if reliability is the most important thing for you get the 2005+ GP1300R since it has no power valves. ( power valves are good for midrange but have their relability issues

    how many hours ? does it still have the cat converter and did the previous owner use Yamaha oil if it still has the cat. water test it . should go about 60-65 mph. if not cat may need replacing with d plate. i was told that the cats fail at 100 hours but i have 130 on mine ( bought with 93 hours ) .

    First welcome to the Hulk. About the ski, Check compression. Also find out if it has had the cat removed & D-plate installed. Do not worry about the oil injection systems ... they have been good on all models after 2004. Take it for a water ride test if possible. They are unique to ride ... remember, it is a Yamaha and therefore very sturdy & reliable ski. If you have not ridden one they tend to Chin-walk @ 23 to 29 mph on the speedo. We call that the "Happy Dance", No worries. If it looks clean & seems to sound right .... meaning no pings or knocks .... it will most likely be a good buy. The going price now for a good clean/running 2005 GP1300 R, is around $3K to $4K. Good luck & keep us posted

    +1. good advice.

    The 2005-2008 are mechanically identical. The last generation with the latest technology.
    -they might cost a little more but definitely worth it.
    Fuel injected non-powervalve engine. (the PTO piston should run ~5psi less compression)
    Large hub jet pump. (with dynafly prop a great pump)
    One-piece ride plate inserts. (The most important difference IMO)

    You can make this ski run 68mph without lifting the seat.
