Lower Unit

Your lower unit is one of the hardest-working components on your outboard motor. At Blue Water Marine, we provide professional lower unit service and repair to keep your engine shifting smoothly, running efficiently, and protected from costly damage.

If you’re boating in Newfoundland waters, especially saltwater, regular lower unit maintenance is essential.

The lower unit (also known as the gearcase) is the bottom portion of your outboard motor, responsible for transfering power from your engine to the propeller. It houses:

• Gears

• Driveshaft

• Propeller shaft

• Water pump

• Gear oil
