Also if you get to a launch and your hubs are too warm then launching in water that is cooler than the hubs will cause the inner seal to contract and water gets inside. If you can wait for then to cool then this will not occur. Lots of people over grease and damage the seals and blows out the back seal. The tires should be taken of each year so the lug nuts don't seize and check bearings as well.
