The OJ Flex Gland is a dripless shaft seal system with no water feed making it much easier and convenient than the rest.
OJ Props has developed the first dripless shaft seal that doesn't require a water feed from the engine making retrofit installation much easier without the need for additional plumbing. Changing to the OJ flex seal in a boat that currently has the plumbing is as simple as plugging in the current waterline. This system was also designed to provide more flexibility in the hose by eliminating the extended housing found on other shaft seals that would rub on the prop shaft when there is a misalignment.
