Pay Now or Pay More Later - Outdrive Cooling Showers Save Outdrives!
Proper operating outdrive oil temperature is crucial for long life. Unfortunately, most stock and high-performance boats today do not offer the ability to monitor outdrive oil temperature, but those in the know can read the signs visually by discoloration and deposits left on the top of the outdrive. An outdrive cooling shower is the perfect cost effective way to add years of service life to your boats outdrive.
This system distributes a continuous supply of cool water onto the upper portion of the outdrive. Tests have shown that extra cooling like this can double bearing life and the service life of the drive oil by lowering an operating temperature of 220° (more than enough to boil water) as much as 30%. It also prevents oil foaming, the primary cause of oil breakdown, which can lead to drive failures. This condition is found broadly across all applications of sterndrives where demands on the drive are consistent and or pushed to deliver maximum performance. As the oil temperature reaches near boiling the oil wants to move away from the main upper support bearing in an effort to escape the excess heat. This is where the oil is needed most.
If there is a continuous need to remove a white chalky deposit from the top half of the drive casing, or steam is generated in the transom area each time the boat comes off plane, it's probably running too hot. The outdrive's cast aluminum construction does not respond favorably to the expansion and rapid contraction caused when a 220° drive is plunged into cool water. Under normal operating temperatures, manufacturers recommend that the oil in their drives be changed every 50 hours. For some of us, 50 hours can be a few weeks' worth of use. Temperature is the key to breaking down the lubrication quality of the outdrive's oil. If you value and care for your boat then demand an outdrive cooling shower every boat needs one.
