I have a 1998 TR -18. There are 2 levers just below and behind the gear shift for the engine. These levers open and close ( via 2 cables) the 2 livewell drain valves. Valve closed livewell stays full of water. Valve open water gravity drains out of livewell. What company made these levers? Are they still in business? Is it possible Flow Rite made and supplied Triton their livewell components? Thanks for any help!
