    Arrow 1165cc '1200' Ficht engines, different power ratings for the same model year?

    Messing around with my pair of 2002 Virage TXi, I noticed that the engine plates (well decal stickers on the stator housing) are different.

    Both are 2002 Virage TXi models, one HIN plate says Feb 2002 build (B202), the other says Nov 2001 build (K102).

    Here are the two plates.
    One says 130HP (2001 EM), the other 135HP (2002 EM,DFI)

    It seems that the engine specs are by the calendar date of manufacture, not the model year.

    What does FEL: 46.3 G/KW-HR refer to?

    Looks like the younger one also has a replacement EMM.
    Actually, I think I knew that already, but had forgotten! EMM service was done at Jay's shop, I believe.

    “Family Emission Level" or "FEL” means an emission level that is
    declared by the manufacturer to serve for the averaging, banking, and trading program
    and in lieu of an emission standard for certification. The FEL serves as the engine
    family’s emission standard for emissions compliance efforts.

    not too surprising our 785 differ by 5 hp from 1998 to 2000 with no apperant difference.
    nov model may be early release other is probable final release. bet there no dif at all.

    To add to what CrazyA already said...the G/KW-HR is the weight of emissions given off per unit of power, per hour. I'm sure its CO, but could be HCs. Kilowatt is just another way of measuring an engines power output.

    Family Emission Level - Apparently FEL is HC+NOX, in grams per hour, per horsepower, tested over five modes (weighted);

    Mode 1 = Wide Open Throttle;
    Mode 2 = 80% rpm, 71.6% Torque;
    Mode 3 = 60% rpm, 46.8% Torque;
    Mode 4 = 40% rpm, 25.3% Torque;
    Mode 5 = Idle

    Thanks guys - learn something new every day.

    I wonder if the EMM programming is different between my two motors, and there might be an actual power difference.

    Do they both turn the same RPM and top speed?

    Slightly different max RPM. The newer one turns about 6900, the older one turns about 6800, give or take, depending on conditions.

    I would say the newer one is a hair faster, but I don't have GPS numbers to back that up. Both run right around 60mph, depending on how I sit, water condition, wind, etc.

    Different amounts of clearance between the impeller and wear rings, and different amounts of beach rash on the bottoms. Probably slightly different compression numbers.
