Description
2010 Mariner Optimax 150HP
2010 Mariner Optimax 150HP The 2010 Mariner OptiMax 150HP is a fuel-injected, two-stroke outboard motor known for its power and efficiency, though it is often associated with problems like air in the oil reservoir causing low-oil pressure alarms. It’s a V6 engine with a 2.5L (153 cubic inch) displacement, and common performance characteristics include good holeshot acceleration and low vibration levels, though it can be noisier than four-stroke alternatives. Key troubleshooting for this model involves checking and bleeding air from the oil tank to resolve the 4-beep alarm.
-
Fuel Injection:The OptiMax system features two-stage direct fuel injection, which improves fuel distribution and enhances fuel economy compared to traditional two-strokes.
-
Power & Torque:It’s a V6 engine designed for strong, instant holeshot (acceleration) and good overall performance across the RPM range.
-
Weight:The 150 OptiMax is relatively light for its power class, which can be an advantage for boat performance and balance.
-
Reliability:The engine is built to be tough, with Mercury’s extensive testing designed to ensure reliability.
-
Sound:While powerful, the OptiMax engine can be noisier than newer four-stroke competitors.
-
Air in Oil Reservoir:A common issue is air getting trapped in the oil tank, leading to recurring 4-beep low-oil pressure alarms.
-
Troubleshooting the Alarm:To fix this, you need to remove the cowling and bleed the air from the small oil tank on the side of the engine.
- Propeller Selection: Ensure the correct propeller pitch is used, as the wrong pitch can affect performance and fuel economy.
- Oil Levels: Always maintain correct oil levels and use fresh oil to prevent damage.
- Vibration: While generally smooth, low vibration, check for any loose fittings that could allow air into the oil system.
