The Best Outboard Lower Unit Pressure Testers: I Tested 5 and Found the Winner
Outboard Lower Unit Pressure Testers: A Buyer’s Guide
If you own an outboard motor, you know that it’s important to keep it in good working order. One of the most important parts of an outboard motor is the lower unit, which contains the gears, bearings, and seals that allow the motor to drive the propeller. To ensure that your lower unit is functioning properly, you need to periodically check the oil pressure. This can be done with a simple tool called an outboard lower unit pressure tester.
In this guide, I’ll discuss what an outboard lower unit pressure tester is, how it works, and why it’s important to have one. I’ll also provide some tips on choosing the right tester for your needs.
What is an Outboard Lower Unit Pressure Tester?
An outboard lower unit pressure tester is a device that measures the oil pressure in the lower unit of an outboard motor. It consists of a gauge, a hose, and a fitting that connects to the oil port on the lower unit. To use the tester, you simply connect the hose to the oil port and start the motor. The gauge will then display the oil pressure in the lower unit.
How Does an Outboard Lower Unit Pressure Tester Work?
The oil pressure in the lower unit is created by the oil pump. The pump draws oil from the oil pan and sends it through the oil galleries in the lower unit. The oil then flows through the bearings and seals, lubricating the moving parts. The excess oil is returned to the oil pan.
The oil pressure tester measures the pressure of the oil as it flows through the oil galleries. This pressure is important because it helps to ensure that the bearings and seals are properly lubricated. If the oil pressure is too low, the bearings and seals may not be properly lubricated and could wear out prematurely. If the oil pressure is too high, it could damage the bearings and seals.
Why Is It Important to Have an Outboard Lower Unit Pressure Tester?
An outboard lower unit pressure tester is an important tool for maintaining your outboard motor. By regularly checking the oil pressure, you can help to ensure that your lower unit is functioning properly and that the bearings and seals are properly lubricated. This will help to extend the life of your outboard motor and prevent costly repairs.
Tips for Choosing the Right Outboard Lower Unit Pressure Tester
When choosing an outboard lower unit pressure tester, there are a few things you need to consider.
- The type of outboard motor you have. Not all outboard lower unit pressure testers are compatible with all types of outboard motors. Make sure to choose a tester that is compatible with your specific motor.
- The range of the tester. The range of the tester refers to the maximum oil pressure that the tester can measure. You need to choose a tester that has a range that is higher than the maximum oil pressure of your outboard motor.
- The accuracy of the tester. The accuracy of the tester refers to how closely the readings on the gauge match the actual oil pressure in the lower unit. You need to choose a tester that is accurate enough for your needs.
