    250 Pro XS vs 250 XS?

    I am looking into buying a 250 XS or Pro XS was wondering, besides the lower unit what are the differences? I will more than likely get another sportsmaster lower no mater which Motor I select.

    I know that the Pro XS can run 89 octane and the XS has to be high octane, correct?

    Also i am being told that the rev limiters are different. Can someone tell me what are the normal rev limiters on these two motors? I would think that the XS should have a higher limiter being its the racing motor, but i would like to get some of the questions answered before i pull the trigger on one.

    Any comments on owners of these two would be appreciated.

    The 2003, 2004 and 2005 were called 250 XS , they were assembled by the race dept called the Mercury High Performance Group and required premium 91 min octane .. The 2003 and 2004 had a low rev limiter of 5850 but the 2005 had the high limiter of 6300 which is the same from then till now.. The Pro XS showed up in 2006 and was assembled by the regular mercury production dept and was the first year of the usage of 87 min octane fuel... The 250 DFI engines available today are the Sport XS and the Pro XS .. The Sport XS is assembled by the race dept and comes with a Sportmaster gearcase and calls for Premium plus oil . The Pro XS is assembled by the regular production dept and calls for DFI oil and comes with the Verado case with other gearcase options such as the Torquemaster... Both the Sport XS and Pro XS use 87 min octane and have the same rev limit. Mercury lists them both as having solid motor mounts and the Sport XS as having 187 KW of power while their listing for the Pro XS shows 184 KW of power.. Seeing as how Mercury lists the Sport XS with 3 more KW of power and that they come standard with the Sportmaster you plan to run, that looks like the better choice ...

    Darby:

    The powerheads, electronics, fuel system- virtually everything INSIDE the cowling are identical on current production models.

    Adapter plate, upper mounts, and gearcase choices are the primary differences.

    If you want the Sporty, you'll need to go with the Sport XS.

    There is a difference in the warranty also, 2 years on the XS engines, and the Pro XS engine have a 3 year warranty, Mercury usually runs a promotion with a additional 2 years of warranty on the Pro XS engines, you will have to look into that yourself to see if the promotion is still going on currently, it is usually called 3+2 or 5 and drive. The last 2 years of the warranty are not a full warranty as the first 3 years are.
