225 std. Opti cowl vs 250xs cowl?

[aaronmt73]

I just installed a 03 or 04 250xs powerhead on my 2006 standard opti mid.I changed the tuner as well as put in solid mounts.Just got it out of break-in mode and its running great.My question is although the 225 std. opti cowl appears to be the same on the outside,is the ducting on the inside the same?Could someone show me pics of there 250xs cowl on the inside?I got to think my 225 ccowl is a lil more restricted then the 250xs cowl.Any pics or ideas?I know air is critical and to much will lean it out,however not enuff isnt good either.Thanks Aaron

I know the 250XS air box has a 3" hole cut in it right over the EFI intake. I believe the cowl itself is the same air intake wise.... Maybe a dealer/tech will confirm this....

Thanks guys,looks like it the same as mine.Now I think I just need to get the newer ecu flash.Mine has the 5950 limiter.The 05 and newer have the 6400 limiter,that would be better by far.With 4 in the boat a 25p and a bit over 1/2 tank of gas we were able to hit the limiter.
