Aluminum Alloy Fishing Boats Often Encounter Malfunctions

What are the common problems of aluminum alloy fishing boats? We often encounter that the machine cannot start; the machine can start but does not operate normally; the machine suddenly dies at high speed. Processing method:

1. The machine does not start

a. Check if the insurance card is inserted.

b. Check the circuit  from the battery power-battery head-battery line-start motor relay-start motor-spark plug-spark plug-high voltage package-electronic box-charging coil-pulse coil to check.

c. Oil circuit part: Are there oil from the oil tank and the air bolts are unscrewed? Is the oil pipe connected correctly? Is the oil nozzle blocked? Is there any debris or water in the oil cup? Is the oil pump working? Is the carburetor filled with water? Whether it is clogged, whether it is atomized, and whether the intake cuts are damaged.

d. The head part needs to be inspected and repaired by a maintenance master.

2. The machine can start but does not operate normally

a. Circuit part: Is the ground wire loose? Some spark plugs are not working properly—The high voltage package is damaged—The electronic box is not working properly—The pulse coil is not working properly.

b. Part of the oil circuit: the oil pipe is ruptured and there is oil leakage — the oil nozzle is clogged — there is water in the oil cup — the oil pump diaphragm is ruptured — the carburetor is clogged — the intake valve is leaking.

c. The temperature of the cooling water is too high, the pump impeller is damaged, the inlet channel is blocked, and the short cylinder works.

d. The head part: the piston and piston ring are damaged; the pulling cylinder—the bearing is damaged—the crankshaft connecting rod is damaged. A maintenance master is required to check and repair.

3. The machine suddenly dies at high speed

a. Check if there is oil in the oil tank. Check whether the oil pipe has fallen off or cracked.

b. If the temperature is too high, the electronic box controls one or more cylinders to stop working.

c. Individual spark plugs were suddenly damaged and the iron wire fell off. The coil was suddenly damaged.

d. The piston and piston ring are suddenly locked, the bearing is scattered, take less lubricant or use the poor quality lubricant connecting rod to penetrate the cylinder crankshaft deformation.
