Well, I took it in and got the impeller replaced, then I took it out to the lake and it ran like crap, I couldnt get it to top speed. I took it back they ran diagnostic tests, checked the tps, plugs, coils, sensors, but nothing would come out on the computer. They said that they made a few adjustments (not sure to what) so I went to test it yesterday, and upon take off it is very sluggish, it took about 30 seconds to get some speed and plane out. I can get closer to top speed (water was a bit too choppy) but it just doesnt have the power it had before I took it to them, they are an authorized Merc dealer by the way. Any ideas on what could be happening with my engine? Thanks, RickLast edited by chopperwolf on October 22nd, 2009, 10:48 pm, edited 2 times in total.
