    Default SE121 Bravo Lower Mods

    You show on the website that the new SE121 Bravo lowers can be modified to fit the early Bravos. What sort of mods are required?

    Thanks, Ken

    The oil passage in the waterway has to be plugged on early models that do not have the passage in the upper. It is best to drill and tap the hole and install a set screw with sealant. Make sure to place the screw flush or slightly below the surface.

    thanks for the quick reply..........

    unique situation here in that my boat is newer, 1997 but unsure of outdrive age, know that it is older than the boat.

    Before putting on the 122 to my Bravo upper how can I verify if I need to block the oil passage or not?

    The easiest way is to simply compare our unit to your original. Check for the oil passage hole in the water passage.
