Why does Kohler 4EOZ emit black or gray exhaust smoke?
If your Kohler Marine Equipment engine emits black or gray exhaust smoke, use the correct fuel. Service the air intake screen if it's clogged or dirty. Drain out surplus if the lube oil level is too high. Use the correct viscosity oil if the lube oil is incorrect.
What causes abnormal noise in Kohler 4EOZ Marine Equipment?
If your Kohler Marine Equipment makes abnormal noise, add lube oil if the lube oil level is low and tighten the hardware if there is a loose bolt or screw.
What causes high lube oil consumption in Kohler Marine Equipment?
If your Kohler Marine Equipment has high lube oil consumption, use the correct viscosity lube oil if the oil is too light or incorrect. Check for leaks in lines, around the gasket, and the drain plug if there are oil leaks. Clean the breather system if it's clogged.
What causes low lube oil pressure in Kohler Marine Equipment?
If your Kohler Marine Equipment has low lube oil pressure, add lube oil if the lube oil level is low. Drain and fill with the correct lube oil if the lube oil viscosity is incorrect. Replace the shutdown switch if the oil pressure switch is inoperative.
Why does my Kohler Marine Equipment starter crank slowly?
If your Kohler Marine Equipment starter cranks slowly, check the electrolyte level and specific gravity (for batteries with filler caps only) if there's low battery output. Use proper viscosity oil if the lube oil is too heavy. Clean and tighten loose connections if there's loosened or corroded wiring.
What causes a Kohler 4EOZ Marine Equipment engine to knock?
If your Kohler Marine Equipment engine knocks, use the proper fuel type, consulting the fuel supplier if needed and bleed air from injectors.
What to do if Kohler Marine Equipment starter does not work properly?
If your Kohler Marine Equipment starter does not work properly, clean and tighten the loose connections. Check the electrolyte level and specific gravity (batteries with filler caps only) and check battery voltage if there is low battery output power. Replace the starter solenoid if it's inoperative. Replace the switch if the start/stop switch is inoperative. Check the wiring if it's inoperative.
What causes high fuel consumption in Kohler Marine Equipment?
If your Kohler Marine Equipment has high fuel consumption, use the correct fuel. Service the air intake screen if it's clogged or dirty. Reduce the load if the engine is overloaded. Check the thermostat if the engine temperature is low. Check for leaks at the fuel tank, lines, and engine fuel system if there is fuel leakage.
How to reduce noise from a Kohler Marine Equipment unit?
If your Kohler Marine Equipment is noisy, check the exhaust system for leaks and ensure it's securely installed, looking for loose parts. Inspect the vibromounts for any breaks or damage. Check the clearance to ensure the unit isn't hitting the craft structure or compartment. Install approved insulation if there's no compartment sound insulation. Tighten all bolts if there's loose or vibrating sheet metal.
How to troubleshoot a Kohler 4EOZ that will not crank?
If your Kohler Marine Equipment won't crank, it might be due to a weak or dead battery. Try recharging or replacing the battery. Also, check for reversed or poor battery connections, ensuring a good ground. Inspect the circuit breaker in the controller and reset it if it has tripped. Check the function of the start/stop switch, and replace if necessary. Similarly, examine the starter solenoid and wiring, replacing if needed. As a last resort, attempt starting by direct connection to the battery; repair or replace the starter if it's inoperative.
