Seakeeper Gyro Stabilizers

O.J.’s Marine are certified custom Seakeeper installers.

Certified Dealer for Seakeeper Stabilizers and Certified Service & Installation Center

how the seakeeper stabilizers work

Inside a vacuum encapsulation, a flywheel spins at speeds of up to 9,700 rpm. When the boat rolls, the gyro tilts fore and aft (precesses), producing a powerful gyroscopic torque to port and starboard that counteracts the boat roll.


Hightech stabilizers

Seakeeper is a computer controlled gyroscope that eliminates most boat roll, including the fatigue, anxiety, and seasickness that go with it.


Flexible Stabilizers

Our models can accommodate boats over 30'. They can be installed virtually anywhere on board. This flexibility means that approximately 25% of the units we ship are installed aftermarket.



Typically, the Seakeeper weighs between 2% - 4% of boat weight, half or less the power of air conditioning, and fits in available space in the back half of the boat.

Drive System Alignment Specialists

Our trained technicians will make sure your boats’ drive system alignment is adjusted to maximize efficiency in the water and the life of your boat. Whether it is your boats' shaft, engine or cutlass bearing alignment, replacement, or ....., we will make sure they run true.???
