I bought an 02 OB about a month ago with 167 hours on it. It has virtually new plugs and wires and everything else looked good. The prop is a 13 X 11.5 OJ. I just wasn't getting the holeshot I expected out of this 310 hp inboard (I've skied behind a 165 hp I/O for 22 years and the OB wasn't much better).
The fuel filter was the culprit! I don't think it had ever been changed. Although I could blow through it easily, it must have been restricted b/c today was beautiful. On a WOT deep water start, I had to focus quite a bit not to be pulled over the front of the ski.
Amazingly, I think it used less fuel too!
On another note, it seems to run hotter than I think it should. I replaced the impeller b/c of it, but she still runs consistently around 180 (granted it was 100+) degrees outside, but the water temp is around 70.
