REPAIR
At Marine Squadron, we pride ourselves on taking on the most difficult and complex engine repair jobs that others often shy away from. Our highly skilled technicians, many of whom are engineer-trained, have the expertise and equipment to diagnose and repair even the most severely damaged systems.
Unlike other service providers who may offer quick fixes or band-aid solutions, we take a thorough, professional approach to every repair. When your engine fails, we don’t just swap out parts and call it a day; we dive deep into the core of the issue, ensuring every problem is addressed and corrected with precision.
MECHANIC DIVISION
Engine Sputtering or Losing Power
Your engine runs but lacks power or sputters during acceleration.
This often indicates a clogged fuel filter or fouled spark plugs. Inspect and replace the in-line fuel filter if it’s dirty, and check the spark plugs for wear or deposits, replacing them as needed.
Engine Overheating
The engine temperature rises above normal operating levels.
Check for adequate coolant levels and ensure the water intake is free from obstructions. Inspect the water pump for proper operation and consider replacing the thermostat if overheating persists.
Engine Won't Start
The engine fails to turn over or start.
Ensure the fuel tank has sufficient fuel and the fuel valve is open. Verify that the battery is charged and connections are clean and tight. Check the ignition switch and safety lanyard to ensure they’re functioning properly.
Battery Not Charging
The battery doesn’t hold a charge or depletes quickly.
Inspect the alternator belt for wear or looseness and replace if necessary. Check battery terminals for corrosion and clean them. Test the alternator’s output to ensure it’s charging the battery correctly.
Electrical Equipment Failure
Electronics or lights malfunction or don’t operate.
Examine fuses and circuit breakers for any that are blown or tripped, replacing or resetting them as needed. Inspect wiring for signs of corrosion, damage, or loose connections, and repair or replace faulty wires.
Engine Stalls at Idle
The engine runs but stalls when idling.
This could be due to a dirty idle air control valve or clogged fuel injectors. Clean or replace the idle air control valve and consider using a fuel injector cleaner to remove deposits.
Propeller Vibration
Excessive vibration felt when the engine is running.
Inspect the propeller for damage, such as dents or bends, and ensure it’s securely tightened. A damaged propeller should be repaired or replaced to prevent further issues.
Fuel Odor in Cabin
Smell of gasoline inside the boat.
Check for fuel leaks in the lines, connections, and tank. Ensure the bilge is clean and ventilated, and repair any leaks immediately to prevent hazardous conditions.
Steering Difficulties
Hard to steer or unresponsive steering.
Examine the steering system for leaks, low hydraulic fluid, or mechanical obstructions. Lubricate moving parts and top off hydraulic fluid as needed.
Engine Misfires
The engine runs unevenly or backfires.
Inspect spark plugs and ignition coils for wear or damage, replacing them if necessary. Check the timing and adjust if it’s out of specification.
Corrosion on Electrical Connections
Electrical components fail or behave erratically due to corroded terminals and wiring.
Inspect terminals, connectors, and wires for signs of corrosion. Clean affected areas using a wire brush or contact cleaner. Apply dielectric grease to connections to prevent future corrosion, and consider using heat-shrink tubing or sealed connectors in high-exposure areas for added protection.
Trim Issues
Boat doesn’t plane properly or has difficulty trimming.
Check the trim tabs and actuators for proper operation. Ensure there’s no debris obstructing their movement and that the hydraulic system is functioning correctly. Redistribute weight to lower levels in the bow or cabin to improve trim balance and performance.
Excessive Exhaust Smoke
Thick smoke emitted from the exhaust.
Identify the smoke color: blue indicates oil burning, black suggests a rich fuel mixture, and white points to water intrusion. Address the underlying cause accordingly, such as checking for oil leaks, adjusting the fuel system, or inspecting for coolant leaks.
Bilge Pump Failure
Bilge pump doesn’t activate or remove water.
Test the pump by manually activating the float switch. Check for blown fuses, corroded wiring, or a clogged intake, and clean or replace components as necessary.
Navigation Lights Not Working
Navigation lights fail to illuminate.
Inspect bulbs for burnout and replace if needed. Check wiring connections for corrosion or looseness, and ensure the switch and fuse are operational.
Depth Finder Inaccuracy
Depth readings are incorrect or erratic.
Clean the transducer to remove marine growth or debris. Verify it’s properly mounted and that there are no air bubbles interfering with its operation.
Windlass Malfunction
Anchor windlass doesn’t operate or is sluggish.
Check the circuit breaker and ensure adequate power supply. Inspect the motor and gearbox for signs of wear or damage, and lubricate moving parts as recommended.
Gauges Not Functioning
Instrument panel gauges are inoperative or display erratically.
Examine the wiring harness for loose or corroded connections. Test individual gauges for functionality and replace faulty units.
Throttle Response Lag
Delay between throttle input and engine response.
Inspect throttle cables for wear, corrosion, or improper tension. Lubricate or replace cables as necessary, and ensure the linkage is free of obstructions.
Water in Fuel
Engine performance issues due to contaminated fuel.
Drain the fuel tank and replace it with fresh, clean fuel. Inspect and replace the fuel-water separator and any inline filters. To prevent future contamination, ensure fuel caps are properly sealed and consider using a fuel stabilizer or additive designed to disperse water. Regularly inspect the fuel system for leaks or condensation buildup.
Maintaining your boat’s engine and electrical systems is crucial for a safe and enjoyable experience on the water. Here are 20 common issues, along with practical steps to diagnose and address them. Remember, while some problems can be resolved with basic troubleshooting, others may require professional attention.

Upgrade to Hydraulic Steering
Say Goodbye to Slack and Stiff Handling!
Tired of sluggish, unresponsive cable steering? A hydraulic steering system gives you precise control, smoother handling, and zero slack – just like your car! Learn why upgrading is the best move for your boat.
Traditional cable steering is outdated, unreliable, and prone to wear. If your boat’s steering feels stiff, delayed, or unpredictable, it’s time for an upgrade! Hydraulic steering eliminates slack, reduces effort, and provides smooth, effortless control in any conditions. Discover why more boat owners are making the switch and how we can install a system tailored to your vessel.
