HYDRO-SURGE GRATE
The hydro‑surge grate is spring‑loaded. If the intake gets plugged,
the pump suction will pull open the grate, and the water will push
the blockage pass the grate and clear the intake.
If operating the boat at slow speeds in weedy areas, the water
intake grate can become plugged with weeds. A plugged grate
causes the pump to cavitate during acceleration (over‑revving
without thrusting the boat).
If the grate becomes plugged:
1. Slowly advance the throttle to get the boat up on plane, making
sure not to cavitate the pump.
2. Continue to advance the throttle until the boat is running at top
speed. The force of the water should clear the pump of any
remaining weeds.
Fuel System
!
WARNING
Fuel is flammable and explosive. Ensure that the key switch is
off and the lanyard is positioned so that the engine cannot start.
Do not smoke or allow sources of spark or open flame in the area
while servicing. Keep the work area well ventilated and avoid
prolonged exposure to vapors. Always check for leaks before
attempting to start the engine, and wipe up any spilled fuel
immediately.
Before servicing any part of the fuel system, stop the engine and
disconnect the battery. Drain the fuel system completely. Use an
approved container to collect and store fuel. Wipe up any spillage
immediately. Material used to contain spillage must be disposed
of in an approved receptacle. Any fuel system service must be
performed in a well‑ventilated area. Inspect any completed service
work for signs of fuel leakage.
FUEL LINE INSPECTION
Visually inspect the fuel line for cracks, swelling, leaks, hardness,
or other signs of deterioration or damage. If any of these conditions
are found, the fuel line must be replaced.
