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.
