Going to replace my cable steering with hydraulic steering. I have a 1998 Stratos 273 (17'3") boat with a Johnson 150 fitch fast strike outboard. Does anyone know the formula for converting cable length to hydraulic hose length? I know you use longer hose. So far all the Sea Star sites can't give me an answer. Been transferred to three different phone numbers and the last one was no longer in use. Would appreciate any help. Thanks in advance. Brushawg
