Problem 2: Electrical wiring problem
Electrical wiring can become corroded, damaged, or loose, leading to various electrical issues. The solution is to ensure proper grounding and repair damaged wiring regularly.
Problem 3: Starter motor issues
The starter motor is responsible for cranking the engine. When the Evinrude intruder 150 starter motor fails, the engine doesn’t start. The main cause here is worn-out parts and electrical shorts. The solution is to ensure proper wiring and if it’s not fixed yet then replace the starter motor.
Problem 4: Battery charging problems
Due to worn-out batteries, damaged alternators, and electrical shorts the battery of the Evinrude intruder 150 can face several issues. If there are issues, the battery may not charge correctly, leading to starting issues. The solution is to test and replace the charging system components if necessary.
These are the most common electric system malfunctions of the Evinrude intruder 150. However, if you own blue wave boat then you can also face some related electric system malfunctions. You can check all the Blue Wave Boat problems here.
Evinrude intruder 150 Cooling System Problems

The cooling system is responsible for regulating the temperature of the engine. Here are some of the common cooling system problems and their possible causes and solutions:
Problem | Cause | Solution |
Overheating | Clogged cooling passages, malfunctioning thermostat, low flow | Inspect and clean cooling passages, replace the thermostat, inspect water pump impeller |
Water pump failure | Worn-out parts, debris in water intake | Inspect and replace damaged components, regularly clean debris from the water intake |
Thermostat malfunction | Stuck thermostat | Replace the thermostat |
Clogged cooling passages | Debris and corrosion buildup | Regularly clean and flush cooling passages |
Problem 1: Overheating
Overheating issues in Evinrude intruder 150 can occur due to a clogged water intake, low coolant level, or a malfunctioning thermostat. The solution is to inspect and clean the water intake, check and refill the coolant, or replace the thermostat.
Problem 2: Water pump failure
The water pump is responsible for circulating coolant throughout the engine. The Evinrude intruder 150 water pump fails due to worn-out parts and debris in the water intake. As a consequence, the engine can overheat. The solution is to replace the water pump.
Problem 3: Thermostat malfunction
The thermostat regulates the flow of coolant throughout the engine. If it fails, the engine may overheat or run too cold. The solution is to regularly clean debris from the water intake or replace the thermostat.
Problem 4: Clogged cooling passages
Cooling passages can become clogged with debris or scale, preventing coolant from circulating. The solution is to clean and flush the cooling system regularly.
