THE BRAVO® COOLER HOSE KIT is another great addition to your stock Bravo® drive as it cools the drive, lowering the gear oil temperature while under way, prolonging the life of the drive substantially. It acts like a shower of high pressure water, spraying directly over the upper gear case. It is easily installed on your Latham Marine steering mount as the connection port is already there! Drill two holes on the drive anti-cavitation plate using the template supplied with the instructions, attach the water pickup then simply hook the cooler hose to the top of the steering mount and you are ready to go!
