Opti 250 Pro XS down on power
Guys, i have a 2010, 250hp pro xs that isnt making the power it should.
Terrible holehsot with a 24 bravo 1 on a light bay boat. Top end is weak also, 57-58 mph where the same setups are low to mid 60's
Compression is good on all 6, i pulled the plugs and it looks like the port bank is running richer than starboard. I have heard the coils are problematic on these motors.

I would say the star bank is lean. The left looks closer to normal for a 2 stroke burnlng oil. Coils and drivers and connectors need to be checked since it is 2010. Spark check tool /and or a timing light to verify good spark.

Check to make sure the thermostats have no debris in them. If hung open and not allowing the motor to come up to temp it will run rich on a bank or both. hf...

With no codes or other signs, you can probably start with the cps.
Bot it coming out of the whole bad is tps or throttle body synch.
Next comes plugged up carboned exhaust.
