    Cold Water and Carbs SXR 800

    Learnt something about my jet ski. The last two times out has been cold water (mid 40s and air in the mid 60s). I developed a real bad hesitation when letting off and reapplying throttle. I thought I might have to rebuild carbs and fuel pump. I richened up high and low speed screws 1/8 of a turn. That fixed it. It was great today (43F air and water). I might have been a little lean all along. I switched from 60:1 to 43:1 and the carbs still had there stock settings. Summer was fine.

    When the air is in the 50's or less your fuel mixture is leaner & you are also dealing with colder water that makes it harder for the motor to come to proper temp & seizure is def possible.

    Does anyone, try to throttle outlet water from the engine to increase temperature?

    Also, when you go from 60:1 to 43:1 you lean it out a bit more.
    43:1 is a "more oil less fuel mix" which = less fuel to air. Splitting hairs here but worth noting.
