Drive Oil Reservoir Bottle overflows:

The Drive Oil Reservoir Bottle overflows because the drive oil has overheated to a point were it is expanding. Because it is a sealed system, it has no where to go except the reservoir bottle. The design of the reservoir bottle is to receive a normal amount of oil under normal circumstances. If the drive oil becomes overheated, it expands more than the amount meant for the bottle to handle and it overflows.

This is what some of our customers said regarding this problem:

Keep in mind that however hot the casing is, the components inside are running much hotter. Published test results show that some stern drives components operate in excess of 350 degrees F. If you are experiencing any or all of the above conditions, your drive is probably operating over 250 degrees. For the same reasons that automotive engineers established approximately 200 degrees as an optimum operating temperature for their engines, most marine experts agree that this also holds true for stern drives. Even MerCruiser will admit that 300 degrees is flirting with disaster. That's the temperature at which the oil begins to foam and break down. It loses the ability to lubricate the components inside the drive, causing them to freeze and destroy the inside of the drive. It is commonly referred to as “the drive grenading”.
