TILLER LEVERS Jefa Tiller Levers are made from high strength aluminum. The Jefa Tiller Levers are available in four sizes depending on the rudder stock diameter. All Jefa Tiller Levers are standard equipped with an autopilot pick up hole at 250mm centers and tap holes for the rudder feedback unit. PYI can bore and key to suit your needs.
DRAGLINKS Jefa aluminum Draglinks create a lighter and stronger solution over stainless steel draglinks (proof stress of 280 N/mm² compared to 200 N/mm² for SS). The articulated rose joints on the Draglink are specially designed from high strength aluminum with a removable Delrin ball. This provides an electrical disconnect of the rudder from the rest of the steering system and boat. The Draglinks can be adjusted 110mm in length. Standard Jefa rose joints have a 16 mm hole, and are also available in imperial sizes for replacement on other steering systems.
