Can anybody tell me if 250 and 300 hpdi connecting rods are the same. If not, what is the difference between them? Thanks!

Not the same. Different part numbers.

69L-11650-00-00 YAMAHA CONNECTING ROD KIT
What is the difference? Only the engineers in Japan know. And they ain't talking.
It stands to reason IMHO that a connecting rod for a 300 HP motor might need to be a tad stronger than for a 250 HP motor. My reasoning in the past has been flawed. Might be so this time.
