If cavitation still exists after lowering the outboard, it may be helpful to seek advice from the boat
manufacturer.
Another option to further reduce cavitation is a rough water plate. A rough water plate may be
helpful in reducing cavitation when running in windy, rough water conditions where air is sucked
into the water intake when jumping waves. Install a 0.8 mm (1/32 in.) metal plate that extends
from the hull bottom to the top of the water intake housing. This plate tends to reduce air intake
as well as reduce spray.
