My 2001 250 xb had a WOT of 6100 but the limiter didn't kick in until 6250. Look on the sticker on the clamp bracket were it attaches to the boat.
Operating range on sticker will be about 150 below rev limiter.My 2001 and 2002 model XB's say 6100 operating range so I say 6250. Get you a 300 ignition computer . It has a 6450 limiter and 2 degrees more timing.
