    Folks,

    My 1993 27' SeaRay Weekender (7.4L Bravo 3) won't start.

    It cranks fine with 2 new 800 CCA batteries. I presume it's either a fuel flow or electronic problem. I have "reset" all the circuit breakers in the breaker box within the engine compartment. When I "reset" each of these breakers, there is minimal movement of each of the red button breaker switches, and I consider this to be normal.

    When I try to reset the 50 amp breaker right next to the distributor (the Engine Wiring Harness breaker I believe), there is zero movement of the red reset button, and I suspect this may not be normal. I press the red reset button and it feels as hard as a rock.

    Is this normal behavior for the 50 amp breaker next to the distributor?

    Thanks,

    Bob St John

    That one is usually pretty stiff. But if that breaker was bad, you wouldn't have power at the dash.

    Check your kill switch.

    Check for spark.

    Try starting fluid.

    Any service work done since it last started?

    The only boating kill switch I'm aware of has a lanyard associated with the ignition that should be attached to the operator's wrist (or some other way to the operator).

    This boat does not have that.

    Are you referring to some other type of kill switch? If so, where might that be?

    Thanks,

    Bob St John

    You need fuel and spark. Which one are you missing?

    No, that's the one. It's either on the control box or dash mounted. If it's not there, your boat doesn't have it.
